Stock vs. Logisystems controller wiring?

I called them and asked if I could have a customer send one in and have them take a look at it... after some discussion, they agreed to take it and investigate.

This is not an open door policy yet.
I am waiting to hear from FSIP once they assess the control from 1fastbuggy....

I'm sure he didn't mean to let the cat out of the bag, but again they are not saying they will or can repair Logisystems controllers at this time, we are simply sending them one to look at...... lets just wait a few days and see what they say.

That is understandable. I worked for a company repairing electronics before and you have to be careful you don't get into something that you cannot properly repair or get parts for. I have been doing some reading and the conclusion I have come to is what I thought all along. These controllers are not really all that complicated (at least the Series ones), and the big price tag for controllers that handle 500 amps instead of 300 is mainly due to adding a few cheap mosfet power transistors and resistors. Tricking a stock 36 volt controller into NOT shutting down with 48 volts may take more tweaking but I think I am going to start taking one of these things apart soon for some frankenstein action. I read one guys step by step upgrading a 275 amp Curtis to 550 amps for use in a EV. It was tedious but not rocket science.
