Conversion TimeTruck is a factory EV, no conversion.

Repair time to fix it: from a Sacramento power company that blew-up the controller when they changed out the battery pack to wet cells and re-wired a few too many things wrong.

The FETS were smoked in the controller, along with a few other things, caused by the previous mis-wiring by the power company.

To get the truck working, 12 days labor over three months. Battery pack revamp / install 4 days.
Conversion CostOriginal cost from Ebay as a "running" truck that was really DOA, $5,000. To fix the controller (Lucky there, thanks to Chris) $1,500. Batteries Lead Acid $5K, Battery balance $1,000, Metering $500, Charger $3,000 Total: $11,000
Additional FeaturesWorking on how to get some benefit from using high power solar cells mounted on roof of the truck's bed camper top, to trickle charge the traction battery pack. Need a charge controller with an output of 360 volts DC.
This vehicle was sold to me on Ebay as a 'working truck' but was really DOA. Learning that the seller lied about the condition of the vehicle when I bought it, I was lucky to get all the wiring figured out, put it all back as it should have been and get the controller fixed! Otherwise, I would have had to scrap out the motor and controller and start all over with maybe a Azure Dynamic type motor and controller. Help came from the US Electricar Group at Yahoo.com.

Now, I have a great EV car that is a lot of fun to drive.

Controllers with 3 phase AC motors are way cool! This is the way to go and get free regen braking, re-use the energy lost by braking. See AC-EV Group at Yahoo.com for more information on AC drive systems for electric vehicles.

Look forward to (trickle) charging the truck by an on board solar panels or the solar off the house.

Hey, energy can not be created or destroyed, just moves from one state to another... Using the energy from the sun directly is what we will all need to face up to sooner than later.
