Possible MSD Ignition Issue

[madmaxx]

if you take off the cap and you button is flat it is because the rotor bar was not contacting. Make sure you bend your rotor bar up so that when you put the cap on you have to push down slightly to screw down. This will ensure the rotor bar is touching the distributor cap button.

It is also very easy to test the msd box. read the instructions.

You probably toasted the mag pickup in the distributor. The MSD website has very simple instuctions on how to test it...If it's bad buy 2 and have a spare...

I agree with Rick. Keep a spare coil and dist (ready to go, with fresh cap) on hand at all times.

That covers all the typical points of failure, from mag pickup to broken gears, corrosion, etc.

I almost never see an actual case of the box going bad, but you hear lots of anecdotal stories about them failing. I have a spare one of those, too

And if you do replace the Mag Pickup, remember to set the gap between the reluctor blades and the pickup to no more than .025". Any greater and you will not start....been there, done that.

How did leaving the ignition on burn up the magnetic pick-up??
