RED-Z06 2,481 #1 Posted October 3, 2022 I got my new plug in and as soon as i started messing with the plug it fell apart, wires broke off...so i had no idea where the wires went...so i figured id use bullet connections, 7 wires total. Heres my problem. The engine side has 2 reds...one im assuming goes to the starter for 12v because its always hot. The other is B+ off the regulator. The tractor side only has 1 red. The wiring diagram isnt much help...but it shows B+ on the tractor side as white? Share this post Link to post Share on other sites
RED-Z06 2,481 #2 Posted October 3, 2022 Figured it out...my B+ is red and should be white...white isnt used on tractor side. 1 Share this post Link to post Share on other sites

squonk 42,719 #4 Posted October 3, 2022 9 pin molex connectors are horrible. Add in the proximity to the battery and muffler heat. When I had a 520. I cut the wires way back to there origins. Extended them with new individual connectors and moved the plug connection to the other side of the tractor away from the heat and battery fumes. Share this post Link to post Share on other sites

I was good until i started crimping the pins on and they pulled out...trash Share this post Link to post Share on other sites
rick 245 #7 Posted October 4, 2022 The open barrel connector terminals supplied with Molex and Deutsch connectors are designed to be crimped with an open barrel crimper. Using other pliers to crimp them isn't usually successful. Just sayin'. 1 Share this post Link to post Share on other sites

I used my ratcheting crimper, they just didn't hold well enough. 1 Share this post Link to post Share on other sites
