Subscribed. I just bought one of these 4x4s and am going through a restoration as well. There is a "hidden" switch in the right glove box on the left side that unlocks the full 25+ mph, otherwise it's limited to around 14mph.
What battery are you planning on running? My controller is a 650A but it's a challenge to find something adequate battery wise. Curious if you have experience with this type of output and what you recommend.
I just got a 2008 R&T going and there is not a lot of info out there to help. I had to figure everything out on my own but I now know this cart inside out. Had to replace controller with an Alltrax. Hint, the throttle sensor looks like an ITS but its output is a voltage source sensor. The motor on my cart was completely melted and had to be re-wound at a shop. Looks like most wiring was a mish-mash of “whatever they had on the shelf” because although the wiring was complete, the wire color would change at a connector for no reason at all and this made tracing wiring very difficult. The orange solenoids you pointed to were likely the forward-reverse select and the main contactor. The 4WD select is controlled by 2 automotive relays behind the dash. The 4WD selector servo on the front diff is a Yamaha unit- and mine was also toast. I’m not a RU-vidr (yet…) but HMU if you have any specific question on this R&T!
There was very little parts available and what was available was very expensive. I sold it and moved on to another project. Thanks for your interest, sorry to disappoint you 😢
I decided to sell it…almost no parts available and basically would have had to rebuild everything with different parts which would have been super costly. Decided to focus my efforts on other projects. Sorry to disappoint 😢
