So we just splashed after about 9 months on the hard. We did no engine or wiring work at all.
The engine runs well - vibrates a little at idle for reasons I can't figure out, but runs super smooth just like it did before we hauled. And if it is like it was before we hauled, there's little to no vibration when it's in gear so...
However, this post is because the alternator isn't charging and the ProIsoCharge isn't even coming on. No lights at all when I turn on the ignition and it doesn't come on when the engine is running. I'm 99% certain that without that, not only will it not charge, but the tach won't work either because there's no field. Someone correct me if that's wrong, but I'm fairly sure that's the deal.
I've checked the postive input (from ignition) on the IsoCharge and it's got 12v and the ground is good.
The only thing I can think of is that the sailboat next us on the hard was struck by lightning in December while we were out of town. It made a complete mess of all his electronics, but I tested everything on my boat - EXCEPT for the IsoCharge - just didn't remember to test it. I'm betting it's just fried.
So, if that's the case, and I need to get underway tomorrow, can I use a 1/2/Both selector switch to feed the alternator and put the start and thruster banks on 1 and 2, and charge them both? The house bank isn't as important underway and I have a 30 amp charger wired in that I can switch on when we're on shore power at night to charge it if necessary. The start is a single 12v and the thruster is 2 12v in parallel.
Thanks in advance for any assistance.
