Here's a nagging electrical problem:
I've been having low voltage issues for a long time now despite putting on a new internally-regulated alternator and a new Odyssey battery. I finally got around to hooking test leads all over the place and here's what I found.
Alternator puts out a solid 14.5 volts and that voltage registers just fine all the way to the master switch and the main bus...until I throw the master switch. When I do that the whole system drops to about 12.8 volts. And once I start loading up the system, the voltage continues to drop until I show a discharge.
But of course the master switch just grounds the master relay and connects the charging circuit. So what could be sucking up my voltage?
I've checked all the wires and found no obvious signs of wear or shorting.
Any ideas?
