Hey folks, I've found myself ending up here many times while searching tractor issues in the past so I decided to join today to see if I can get some help and explanations with my charging set up.
The tractor is a super H I've owned since I was 18 it has been a great machine with no troubles other than a couple small annoyances. It is a 12v system with a 3 wire delco alternator. Ever since ive owned it the alt has drawn power even when the switch is off, to the point where within 30 minutes the battery is dead. Not a huge issue just unhook the battery. Fast forward to now. The previous alt finally gave out so I replaced it but while I'm in there and have a little time I want to solve this problem.
Ive found previous posts on this forum about putting a diode or "idiot light" in line from terminal 1 out of the alt to solve this but alot of those guys were having trouble with the tractor continuing to run even after the switch was cut off which isn't happening to me. If this will cure my drainage problem I would probably go the indicator light route as those are alot easier to find in my area vs a diode but being a system I don't fully understand I can't see how a light in line will stop power flow so I guess I could use that explained in simple non engineering terms. Also while I have a little ambition and time I want to swap my old non working amperage gauge to a volt gauge and was curious what that entails.
Sorry for the long drawn out post I hope it comes across as understandable. I appreciate any replies and help.
