Ok things are really starting to move again. I finally got the wiring done and tried powering up the car over the weekend. Couple of minor hiccups which result in 2 warnings.
1) I found out that the ignition switch was connected to earth, The ZAPI controller puts 120V through its power switch which I connected to the old ignition. I then lent over to connect the last battery terminal and boooot, I got a zap and a half. Measured between the terminal and earth - 120V. Warning, check that the ignition switch isn't earthing the main DC supply and before touching any battery terminal measure the voltage to the chassis in case of shorts, 120V can be fatal.
2) I got contactors with a 12V winding which seem to be what most people use in conversions. When I fired it up all looked good, switched the direction switch to forward and click, smoke. The ZAPI powers the contactors with 120V. As you are aware electric components run on smoke and once you let too much smoke out that don’t work anymore, fortunately I didn't let enough smoke escape and the contactor seems to be ok. Second Warning, double check the winding voltage for the contactors. I'm getting a couple of 120V relays to connect to the contactors and will see how that turns out.
So I didn't get any movement but at least I have most of the wiring done and a controller that is not reporting any diagnostic errors, and I survived a 120V boot. With any luck I should have the relays in tomorrow and will give it another go.
