Good morning All,
     I'm at a standstill with my upgrade. I bit the bullet and got and installed a new SR48600 controller, heavy duty main Contactor, f/r contactor, and PB-6 pot box.
     I have the high voltage (big wire stuff) installed, now working on 12 volt wiring. Here's my problem, the diagram from Alltrax shows a direct connection from the main contactor to the ksi switch then to f/r switch then to the micro switch on the pot box then back to the main contactor. It seems clear but that is all low amp 48 volts, the current wiring has a feed from the ksi to the the fuse box at 12 volts. 
      My first thought is to just to run another switch circuit to turn on the 48 volt system with an incorporated DC/DC converter that sends 12 volts to the ksi. My concern with that set up is how the foot pedal input interacts with the f/r switch and the reverse light set up. 
     There was a good conversation thread last year where people sent in their wiring diagrams, the sight may be having issues, I cannot see the photos, the file uploads seem to be fine or email me directly is cool too. 
      This group has been so helpful over the time I have owned my car. I hope to get it running this month and use as a sunny daily driver : )

Hey Tony, I wired mine last year, so I still remember a bit. Sounds exactly like my setup. For the 48v controls I used the old resistor relay to switch 48v on off from 12v key switch. That runs to the footswitch ( to the main solenoid) and the ksi input to the controller. The fnr contactor needs rewiring to switch directly through the fnr switch 12v so that any time key is on it just switches forward or reverse. It can be done by just bypassing the current footswitch wiring using the same wires. I had a main contact failure this year. I believe the main contactor should be mounted horizontal now.?

And... I left the reverse and forward input open and used the original setup. Controller doesn't care.?

Thanks Dave for the reply!?

? ? ? I attached a low res picture of my set up because you mentioned about mounting the main contactor horizontally, it needs to be vertical? And I placed the saved 12 volt solenoid/relay, is that what you were talking about?

? ? ? ?If you have a wiring diagram of what you did, please send it my way,? I almost follow what you are saying. I found some old hand drawn diagrams for the fwd/reverse switch and other dash electronics that were very helpful. They were appropriately named? "mission impossible" haha. Let me know if you would like them.
