As far as component board layout goes. I was wondering if anyone has advice about which components should be close to each other and which should be far away? Which ones should go in a closed box? Should I use solid copper bar between any components or is 2/0 welding cable OK? Any other tips or pointers? 4/0 cable from controller to motor?

Here is a list of the components I have:

144V, 700amp Open Revolt Controller - software limited to 500 amps to start
Anderson SB 350 connector
6 blade fuse holder
Ferraz 500amp 300V fuse - may move up to 700amp fuse eventually
20 amp fast acting fuse
Relay - I think for DC-DC wiring
(2) Curtis SW200 Contactors
500 amp shunt - will have to upgrade to 700 or 1000 if I move to a 700amp system
Curtis PB-6 potbox
Iota DLS-55 DC-DC converter
VBS braking unit

My pack is split between front and back of the car. I probably need another large fuse for the rear pack, correct?

My wiring diagram is here, and here.

I need as many eyes as possible to check the main diagram out, as well as my simplified HV diagram.

Thanks,

I made a new High Voltage diagram which attempts to show the components where they will be on the component board. I also started on a 12Volt diagram. It is in the beginning stages, so please take a look at it and let me know what you think.

Also, latest updates on the blog linked in my signature.

Please check out my build blog. I am having a minor issue with some noises in the tranny.

Let me know what you think either here or on the blog.

Thanks,
Dave

Is there excessive play in the gear box? If you hold one wheel fixed, how much rotation are you getting on the other wheel?

Do you mean while giving it some throttle? I will try to check it out this weekend. What should I be looking for?

I think what he means is- with the car in gear, input shaft locked/held, one wheel held/on the ground,- how far will the other wheel turn before it stops? there should be very little slop in the mesh of gears and bearings.

Yes. Hamsterpower said it better than me. Don't try to hold a wheel when any kind of power is applied.

I get about 1/8 of a rotation on my wheel, with the other wheel held or on the ground, and the input shaft of the transmission isn't turning. I'm not sure how much is acceptable. Excessive play is one possible explaination for the noises when you let off the throttle.

Quick question - What is the best way to attach the throttle cable to the pot box? The little metal piece on the end of the throttle cable does not fit through the holes on the pot box arm. Just curious what some of you have done.
