Continuing to have electrical glitches.
I have had a couple wires come loose when I can fix; and am working on.
Question now is about how the battery switches are wired. Does one battery switch feed the engines and one battery feed the rest of the accessories? I can't remember which I suspect something wrong with, but I believe it is the SB. If I have the Port switch set completely to OFF, and the SB switch set to either 1, ALL, or 2, I can't use any of my dash accessories and switches. They are all dead. Is this normal? Both batteries are charging. I can start both engines, and when ignition is on, both batteries are reading well on the Voltmeter guages on the dash. It appears as though I have to pull both batteries before I can remove the bulkhead inside the rear seat that the switches are mounted to, to check everything.
I realize my question is not clear, but really I am just looking for some insight as to how this all works.
Also, if I turn on more than 3 switches on my dash, they all start to glow, and most of them reverse polarity. (Things turned off turn on.) I did find a spade connector that came loose on the Blower switch, and have not tested things yet, as I have a couple other things I plan to touch up tomorrow.

I afraid I can't be much help but the glowing is likely a ground issue. I had a bad ground and mine did all kind of strange things.

BF28,
Thanks. I did find a loose ground last night. I will fix it tonight. It is my SB switch that seems to be not functioning. Anyone else?

I to have battery switch issues.
I have a 99 32' that seems to power the dash from the sb batt.
If I have the pt on position 2 and the sb on position 1, you would think they would be seperate from each other, but if I run one low on charge and try to start the side with low charge it pulls down the running side with full charge.
It seems to me that there is no way to isolate either side.
I like to run my stereo on one side and save the other side to start both engines, is this possible?
I have tried all battery positions with no luck.
Any chance of getting a wiring schematic?

Brian,
Call me and I'll tell you how I checked mine on the PQ.
Too much to write.

Bill,
Thanks. I will call you after I patch up the things I have apart at the moment.

Brain,
are the batteries grounded together? are you sure there is not a breaker between the dash and the batteries hidden somewhere?

Brian-
I hope you get all the Gremlins worked out soon. Some of us are headed up to Solomons this weekend for the Full Tilt Rally.
I have a Gremlin that I'm also working on, but if it ain't fixed by Friday, He'll be going with me...

Thanks everyone. I can't find any hidden breakers. (?)
I got the glow worked out. Had to rebuild a few daisy chains.
Now the rebirth of the gremlin in a new spot.
Prior to all this:
Turn on Auto Bilge Switch on dash. Auto Bilge Pumps activate. Light on dash switch out. When the Auto Bilge Pumps kick on, the light on the dash switch comes on, then goes off when the pump float switch deactivates.
Now:
Turn on Auto Bilge Switch on dash. Everything works as above, EXCEPT, the light on the dash is always on.
I don't get it. I did not change ANYTHING on this circuit. I have checked everything. I have swapped out the switch with another.
I liked the way it worked before, and while I can live with it now, I want the original way back. Any ideas?? Thanks.
As for the Battery Switches; still looking for answer on how that all works.
