It's kind of strange - but mine didn't come with a ground strap for the transmission. I assumed it was because of the cast iron toploader transmission. :confused:

There should be a large ground cable from the engine to the chassis or battery negative somewhere. If the battery is mounted in the engine compartment, we might run a ground directly between the battery negative and the block.

Jim Holden 03-31-2014 06:54 PM

A braided ground strap can be had for under $20. I would recommend the trans-frame connection even where the battery is on the right footbox and there is a direct connection to the block. With a fiberglass body and rubber motor mounts, more is better...

My battery negative post cable is bolted to the engine block and the black wire from near the starter relay in Patrick's post is bolted to the engine also. There weren't any other grounding straps in the wiring kit. I have grounds to the frame at the front X-member, behind the dash, tailights, headlights (I think). I guess I will pick up a strap and secure between the engine/trans and the frame somewhere.

So we repaired it but it still does not sound right. Ordered a Powermaster 9406 and it should arrive next week. I'll keep the old one around and hopefully won't have any further issues.

Oh yes, I found the grounds. Tightened bolts, etc.

Phil,

Sorry late on this thread. Here's a little history of the "Click of Doom."

If you want to go to the solution directly, go here: Adding a Remote Starter Solenoid to your Chevy, My Way

If you're up for some history, start here, noting the different Ford solenoids and their reliability: First Coast Cobra Club • View topic - Tom's starter CLICK of doom. Solved?

and then make your way to the last message here: First Coast Cobra Club • View topic - Zephyr update June 2011

The final solution, dual solenoids, has worked on the Cobra and the Zephyr for nearly three years and many thousands of miles for each car.

Hope this is of some help,

Tom

Large Arbor 04-03-2014 05:05 PM

Tom,

Thanks for the post. The old CVR has a solenoid on it and I have one on the dash the same as Pat's shown above. I ordered a Powermaster 9406 and we'll see how it works. If this is the worst thing I have to replace, I will be a happy camper.

Ok, so the saga continues. The repaired starter did not sound right and when I pulled it, it had a missing tooth. My guess is it did not disengage the full amount and broke a tooth. Flywheel looks ok. I bought a Powermaster 9406 per the ERA manual and the bolt holes do not line up to a Shelby Aluminum Block. The adjustments do not allow enough movement to make them align. There was only about 3 adjustment locations. So I am off to the parts store in the a.m. to buy another CVR like the old one.

You know a lot of us, both here and on the FE forum, use the OEM big-ass starter motor. You can still get them at Pep Boys and the like for about $50.

Large Arbor 04-05-2014 07:00 PM

New CVR starter 5049M is in and works like a charm! Done!!!

Phil

Large Arbor 04-08-2014 11:10 AM

The two starters are shown below. The Powermaster 9406 does not have enough adjustment on mounting holes for my Bell Housing. The CVR has 360 degrees of adjustment. Pics below.

It looks like I need to revisit this as my starting symptoms have returned. I used a Robb MC starter which appears to have lasted about a year and so I will have to pull it out and look to see if it ate teeth on the ring gear. I am not sure what to do next if this is the case. Perhaps larger bolts, but I think the Robb MC started did not have enough HP to last.

Patrick,
Concerning this wire. I read somewhere else in the from that you installed another ground wire from the manifold to this same location as the black wire. Was that in addition to the black wire or instead?
As far as doing this test, was that with the car running and progressively turning on all the accessories one by one and you watch your amperage grow the more you turned on.
OK,. so I only have a multi-meter, no inductive ammeter. Can I just break the connection and run it thru the multimeter to get the reading?
Thanks...Dave

That strap was a supplemental ground that was in addition to the black ERA ground wire. Yes, I turned on my lights and fans and then measured the current running through that wire and it seemed a bit high. You can not just disconnect the wire and run it in series with your multimeter unless you have a very special multimeter that will measure higher amperage. Most multimeters can only measure very tiny amounts of current that way.

Phil Stop breakin the car
 
Large Arbor Phil if you are having starter problems and have a good battery and starter here's the problem with eating teeth on the flywheel
I had the same problem with a shelby block motor, 3 choices
I don't know which bellhousing you have but if it's a lake wood your mini starter doesn't have enough extendion for full engagement. Does your bell housing have a block protector plate? If yes You need to remove where the starter goes through the hole area and have the starter mount to the bell housing directly. I sabre sawed mine with a metal blade. The thing with this is checking the starter to make sure it is not hitting or rubbing on the block. I had to grind a little of the block to clear this too. Also and this is BIG, Make sure the bellhousing is centered on the block. Alot of problems happen from this not being done. This includes Stock bellhousing and Quicktime or any other ones. Mine with .038" out. After 3 hours of trimming and adjusting I Got it down to .003" max spec is about .005-.007" out of center.I have found that allen head bolt on the blind side of the starter work the best.
Once we know we have the starter mounted deeper for more full contact we need to look at the air gap between the teeth of starter and flywheel. You want about.035". The easy way is to just use the flywheel without the clutch and ingage just the soleniod of the motor. A large paper clip is the correct thickness. You should be able to stick this between the 2 teeth. You don't have to be perfect but in the ball park. The wider the gap the more stress on the teeth of the flywheel. This job is a pain in the A$$. As for the flywheel, you can have just the teeth replace. If the flywheel has been worked hard with cracks and burnt marks, replace it.
I starter with a Tilton starter and worn out 2 drives before finding out what was causing this failure. It's a pain in the butt to jump start the car.
Other side note, if you are running a Lakewood bell housing and a GM input shaft trans, measure the depth of the input to the back of the block. In some cases you have to remove .280" off where the tip goes into the bushing or bearing in the back of the crankshaft. IF you don't you WILL wear out the thrust bearing permaturily. The is a small side note in the instructions from Lake wood on this for FE motors. Not sure about other Ford motors.
The other fix is to go old style starter and hope you have a strong one and heavy cables to handle the 150-250 amp draw on starting the motor. The OEM starters can be a pain in the butt when they are heat soaked for a long drive and will barely crank the motor over. This is the main reason for the mini gear reduction starters and they draw only 70-120 amps.
The last choice is to have the starter mounting surface machined about .250" and this will give you the added extension on the drive to give you almost a full contact area and stop breaking the teeth on the flywheel. Sammy here on CC has done this and it worked good. The only thing a don't like is the fact of a thin mounting surface with 3 small bolts to hold and control the torque twist when starting the motor. If you have a problem down the road with this starter, need to have it machined again to fit and work correctly. This is the best info I have on this problem. Good luck Rick L.

Oh that sucks!
So I need this inductive type to measure higher amps? I think my multi-meter is supposed to measure 10 amps unfused.
So was this with the car running or not running?

Both with the engine running and not running -- for this it doesn't make a difference. With the negative battery cable going to the passenger side head, and the lights and fans having their negative path via the frame, the majority of the current has to run through that one black wire (or something not as good, like motor mounts, brake components, etc.) Adding supplementary grounds, one a strap from the intake manifold to a bolt on the firewall, and the second was a beautifully crafted 4 gauge wire, with crimped and torch soldered ends, that goes from the negative terminal of the battery to the frame itself. Doing all of that brought the current that was running through that little black wire down to one third of what it originally was. And, it could have just been my imagination, but the starter seemed to crank better as well.

OK, good info. I saw your thread with the On the 04 neg lead. I would like to do the same, only in more flexible heavy braid.
I have been trying to learn about clamp meters that measure DC amp all afternoon. There is a plethora of junk out there. Do you have a good inexpensive one you could recommend?

You might want to connect a cable direct from the negative battery terminal to the starter. This is a place where I don't save weight. I use 50 square welder cable. Not sure how that converts into gauge thickness in the US of A.

To check for losses, use a jumper cable - also with a decent area/cable size ("Diesel" engine jumper cable) from your Battery to starter.
