Ausfishers,
I own a 25hp 2 stroke yamaha electric start (please hold the lazy man slurs - i can pull start it if i want).
Recently i installed a minn kota 12v and made some changes to the wiring ie: main isolator, 50A breaker etc. During this process I mistakenly sent to motor the wrong polarity.
As a result I blew the fuse on the starter circuit. After replcing the fuse everything seemed back to normal.
Since then I have noticed my battery level decreasing each trip and after getting my multimeter involved it appears I am not charging. ie I cannot measure a voltage difference when running and not running. I beleive my motor is good for about 6.5A so i expect to see a voltage difference at the battery if charging.
Is it possible that the incorrect polarity has aslo affected my regulator/rectifier? I don't have any manuals or diagram for this motor so I am not exactly sure what the regultor rectifier looks like. I have followed all the wiring to what I belive is the regulator rectifier and when I try to measure resistance across it, i get an open circuit.
Hopefully your combined wealth of experience may be able to shed some light on:
1. What exactly does this regulator rectifier look like, so I know i am testing the right thing.
2. Can the wrong polarity kill it, if so what is involved to replace the regulator rectifier. I assume it is fairly striaght forward.
Many thank in advance to any assistance received.
Cheers.
