7117 not charging

Recommended Posts


If you have 28 volts A.C. on the B+ (center terminal on the reg/rect module), that suggests it could be bad. However, if the B+ terminal is not connected to the battery, then this could be a false interpretation with your meter set to A.C.(the output is actually half wave A.C/D.C at the B+ terminal of the reg/rect; open circuit. What is the D.C. voltage on the B+ terminal? The system troubleshooting checklist is shown on pages 36 & 38 of the Kohler .PDF manual below. Also make sure the ground is good on the reg/rectifier and could be the cause. If the ground is "floating" I can see that you'd have A.C. voltage only on the B+ terminal.

Bought a new aftermarket regulator/rectifier from DB Electric on Ebay for $12 and change, charges great now. We'll see how the aftermarket regulator lasts, but for $12 bucks I figure I can't go wrong.

      Good morning peeps! I’m always searching for helpful information with my AC collection. Hope to find out new information and pass on my own experience in restoration. Here are some pics of my babies. I’m still looking for front rims for the 410 so yesterday I put the 310 wheels on took it for a drive. Working pretty good but still needs some carb work. Gotta get the 310 running next. Have a great day!😁

      It's in pretty sad shape, but yes I have a yellow plastic cap that I'm fairly certain is what you need. PM me your details and I'll get it out to you.
