ISIS update

Pecal · #1 (**permalink**) 10-12-2009, 04:22 AM

I've finally put a bit of time into the wiring - it's easy to get side tracked when there's so much to do. Anyway the wirings almost finished and I'll know soon when I connect a battery if my efforts just go up in smoke!!

This is the Mastercell monted on a hinged plate in the passengers footwell. The 2 connectors receive earthed signals from the various switches and send the message via a CAN cable (yellow connector) to a Powercell module at the front or rear of the car to switch on the the appropriate circuit.

The front Powercell module is mounted on the front of the passengers footwell. The red cables supply current to the module and the yellow connector provides the switching signals. the the outputs go to the front wiring loom via the top white connector.

The rear Powercell is mounted in the boot on the shelf behind the passenger. The red wires supply power from the 4 fusible links on the left. 2 supply the front module and 2 supply the rear. The coil of wires to the right are unused circuits. There are 20 circuits available with the system.
The next step is to take the brave pills and add a battery to the system!!

I need a few more lessons in posting pics...

So Pecal, is it as simple as it looks ?
I ordered mine last week and I'm hoping that it goes fairly well as I'm a bit of a dill when it comes to volts, amps & stuff ( well I really just bit of a dill if it comes to that!

)
Am looking fwd to your results in it.

Peter, just go into your gallery and under image details, click on the different files sizes. This will change the links below the image, which you can copy/paste into another window where you're editing your original post (eg, have 2 web browsers open).

I'm still keen to check out your car one weekend - looks like good progress is being made.

Cheers

Paul

Thanks Sambo.
Rog246, The installation is not too bad. I found that mounting the modules and fuse block took a lot of time - the wiring is pretty straight forward. I didn't integrate the engine wiring loom fully into the ISIS system so I have a couple of relays and fuses for the EFI, fan and fuel pump (although ISIS switches the fuel pump relay).

Hi Peter, looking good. Hope you dont need too many fuses to "debug" the wiring. I had a great one with my loom, whenever I hit the Horn, it would blow a fuse and my EFI Relay wiring was wrong - problem was the only two wires in my loom that were the same colour code were crossed over - murphy's law.

One question that comes to mind was regarding immobiliser etc. I think the ADR says a min of two circuits. If you are using the ISIS as an immobiliser but havent integrated the eng loom, what two circuits are you using? Just thought I'd ask, I am sure you have it under control.

If you're hoping to use the ISIS unit as your immobiliser, make sure it complies with ADR 82. Scroll down this page for more info.

Failing that, I can recommend the Mongoose M80 for $200 which is ADR approved with a 3 point immobiliser, shock and microwave sensors plus boot/bonnet/handbrake kill switches and a well designed keyfob.

From my understanding Isis will immobilise both ignition and starter circuits when security is on. That is how mine is set up.

Thanks for the feedback everyone.
Gregg, The immobiliser function in ISIS controls Ignition, Starter and Fuel pump. Hopefully the Engineer is convinced with the security the system offers. I will feel blessed if I only blow a fuse or 2 during power-up. As long as there is no smoke involved I'll be happy.

So Bob have you finished the wiring up yet ??

Rog, Unfortunately work is taking up too much of my time at the moment.

All wiring to load cells is complete - needs to be tidied up

All wiring for dash is roughed in

Wires to Mastercell roughed in. I was able to keep all Mastercell wiring to the one connector.

Need to install the dash, connect it all up and test.

I have done nothing yet with the EMS other than to allow for power for the computer.

Cheers Bob

Hey Bob how are you going to organize your seat belt warning system ?
Can we use Isis to do that ?

sambo · #13 (**permalink**) 10-15-2009, 03:05 AM

Thanks Bob. Part way through wiring my car with a dedicated ground circuit in copper (not using chassis to earth) and this was the first I'd heard of separate circuits. Certainly makes sense in your application.

SAMBO,

Show us your handy work..........

STIFFY

sambo · #15 (**permalink**) 10-15-2009, 08:06 PM

Stiffy, all laid out on the garage floor awaiting engine loom and computer hopefully next week. I'm not cutting or crimping until I've got all the parts and I know where the computer is going, etc. And every time I go out there I add another circuit... footwell/boot lights, 12v outlet, etc.

Having said that, you won't get any pics until it looks like a $5000 wiring job.

stiffy · #16 (**permalink**) 10-18-2009, 06:07 PM

SAMBO,

I cannot wait to see the pic's. I would never attempt to wire a car, too many things can go wrong (especially with a convertable)..

At least you have a much better working environment now,,

sambo · #17 (**permalink**) 10-19-2009, 03:20 PM

Great progress Peter. I don't suppose you made notes on the Laser column wiring? I've still got a few unidentified wires on mine.

Wodnas · #18 (**permalink**) 10-20-2009, 01:27 AM

Peter,
Sounds like you have made great progress. I wish I was that far. I have taken a different tact. The only thing I am using the Laser column for is the turn signals, high beam, high beam flash and horn. I have installed separate switches on the dash for lights and wipers. I also have the switched earths separate to the loads.

What did you do for the handbrake switch light earth. The one I have only earths through the chassis so difficult to run a separate switch earth.

Bob

Merv and Sharon · #19 (**permalink**) 10-20-2009, 01:52 AM

I didn't use the ISIS system but like Bob used the Laser (II) set up. I have the wiring diagram of that.

Merv

Pecal · #20 (**permalink**) 10-20-2009, 02:57 AM

Sambo,

I have made diagrams of the Laser connectors but I have altered them as earthing for ISIS. Let me know if you can't get any and I'll redraw them.

Bob,

I too have a toggle switch for the wipers and I'm going to change the headlights to a toggle too - the same as you have done.
I have to admit that I have taken the wimps way out for circuits like the handbrake light. I have installed a fuse block that is energised through the ISIS ignition circuit. That gives me some options for discreet circuits like the handbrake. I also have another fuse block energised by ISIS through the accessory switch position for a radio and other future items.
