Voltage or Ground

The battery boost feature that ties both house battery and chassis batteries together, Has a switch on my panel,When I push that switch does it send voltage to solenoid? or does it make a ground for that solenoid ?

Because many people can't read a post without injecting what they think you said..

might as well close this thread, already way off the rails.

Locate your battery boost solenoid. If it has a single control terminal, then it is almost certain to require a voltage applied to that terminal to activate. If it has two terminals, then one would be grounded by a wire and the other would be hot.....which one would be switched by the boost switch should be determined with a voltmeter.

WTF, I never said that house circuits are unfused. I said that usually the wire switched is the hot wire, which is why he shows no voltage at the small wires of the solenoid. The FUSED WIRE goes to one side of the switch and when the switch is closed the power is fed to the solenoid. If he took a resistance reading of the two small wires one would show an open and the other would show a short to ground. The open wire would have the 12 volts on it when the switch is thrown to boost.


Sorry, like every other post, most people put the POST that they are replying to at the top of their comment.

It is the 2 small posts that are my concern. neither is hot with the obvious wires connected.

we have 1 wire that is not marked, it is neither a ground or 12volt hot..
As long as there is no voltage present I assume the 12+ is switched. s/b safe to check continuity to ground.

Usually with any switch, you are turning the hot voltage wire off and on. If you were switching the ground off and on there is always the risk that something could short out the always hot wire on the solenoid.

It should only be hot at two times:
1) when the engine is running and the chassis battery(ies) are charged. (above 12.2 volts
2) when you push the "aux" start button.

Can check with a voltmeter. If the ground is switched I would expect to find 12+ at the coil continuously.

Possibly visual inspection to see if the coil is connected direct to the frame.

The other large post, is open and connected directly to the chassis battery positive posts.

It is the 2 small posts that are my concern. neither is hot with the obvious wires connected.

It's too bad you didn't learn from MrWizard. He has the terminology correct and you still say it wrong. You are one of those that make is difficult for the rest of use that supply correct answers. And no, I'm not hiding behind my keyboard, I'll say it to you face if you want.
