Thanks for the comments, guys.

You can change the timing of the motor for clockwise rotation. It's simple to do. You take out the four bolts holding the brush end on, rotate it to the CW position and put the bolts back in. They have tapped holes in positions for CW, CCW, and neutral timing.

Yes, the standoffs will see some torque. I have a pocket machined into each plate and I faced the ends of the standoffs with a lathe, so they should all sit flat. I'm hoping they can handle the torque.

I'm going to be using a Kelly 650 amp controller. I have a kelly in my electric motorcycle and it's working well for me.

I'm hoping to get a 30 mile range. I base this on what I have read of similar setups online.

I hoped to get more done today, but I'm sitting in jury duty. At least they have wi-fi. I've spent my time designing my pot box. When I get out, I'll go to the shop (where I work) and make some parts.

Cool, I didn't know that they provided all the holes.

This is yesterday's work. I built my electrical panel and started installing the main power cables.

Here's today's progress. I built a pot box. It looks like this controller will only take a 0-5V signal. I dug through an old bag of potentiometers my dad had saved and found one that I think will work. I'm going to power it with my 13.8v dc-dc converter and since I'm only rotating it 90 degrees or so, I should be able to get close to 0-5V out of it.

You can see the power steering reservoir in the photo. I removed the power steering pump and routed both hoses to the reservoir.

Woah, wait on the pot box. The 0-5 volt comes from the Kelly controller, NOT an external power supply. You will blow up the Kelly if you try your idea. I have a Kelly controller, and a 0-5v Pot means that the pot is connect to +5 at the one end, Signal in the middle and GND on the bottom, and all that is attached to the Kelly control connector.

What ever POT you use, you need the full swing, or it's useless.

You have done a really tidy conversion with the Del Sol!

Have you decided on batteries yet?

[BradQuick]

Yes, the Kelly will supply a 5V signal for convenience, but why can't I generate my own 5V signal, as long as they share a common ground?

[BradQuick]

Yes, the batteries are twelve Trojan T-1275's.

what would be the benefit of doing something like this?

The Kelly is probably the most fragile controller out there, and it relies on it's own +5 for software calibration for the throttle, and it's regulated.

The controller is one thing that you NEVER want to deviate from the wiring schematics, because what if you accidently exceed the 5v? Boom de Ada on the proccessor, then you go rocketing off down the road with no control what so ever.
