Re: yamaha controller- what is it?
I can tell by the plug, its a G22, 2005-2007 model year. The controller is a Moric (& generally a pos). Its likely bad if it wont activate the contactor (which you have figured out). Another test, flip the Tow/run to tow for 15 seconds, flip back to run, does the contactor switch on for about 4 seconds then back off? Also, does the reverse beeper operate?
