I wanted to share what I have learned about what it takes to switch out a older T-1 controller to a Newer T-2 controller.
Some of the advantages of a T-2 are higher amperage and the ability to deal with heat that higher HP motors can put on the
I don’t think the T-1 has any issues with the stock 3.5 and 5 Hp motors.
But if you upgrade to the 7.5 or Higher Hp motors your pushing your luck with a T-1.
I installed a 7.5 Ride 4 fun motor and had the controller re programed and with in a week or so I was getting code “-41 Overheating” the T-1 was having issues handling the extra amps the Larger motor was placing on it.
Rebuilding the controller can fix this problem but the T-1s don’t have as much copper in the heat sinks as the T-2s do and rebuilding a T-1 dosen’t add copper for more heat dissipation.
So if you can get your hands on a T-2 and rebuild that then your ahead of the game.
What your going to need to swap out a T-1 to a T-2 is a 10 pin convert cable and a pin 21 to pin 2 jumper.
Here is the 10 pin jumper adaptor that plugs into your Harness and then plugs into the T-2 controller.
Sorry I don’t have part numbers for the Jumper wire but the part number for the 10 adapter is in the photo above.
Edit: Rodney 7/2/16 Adaptor Part # 0106-00678 includes the jumper wire
And I have some updated info. Both T-1 and T-2 are 350 Amp controllers. The T-2 has the ability to handle more heat because the motherboard has more copper.
I was told that the “Thermister” the part that dissipates heat is a common source of issues in controller -41 error code
