Lol...
Layout:
Red wire - to key-on source [or any hot wire to test.]
Black wire - sold ground.
#1 Green wire - gold post on voltmeter.
#2 Green wire - tape it off. (Not used)
Duplex wire end 1 - silver pins on voltmeter.
Duplex wire end 2 - left and right of isolator main post.
Well. I hope when u find the issues.
Shouldn't need to use a relay for a volt meter.
One side of the dual VM is connected directly to the isolator (two leads, both sides of the isolator), which is always hot; the relay is used to switch the ground side. I'm north of 70 and it's a new concept to me but I understand why the relay is necessary - there aren't any switched grounds so we need the relay to do that.Shouldn't need to use a relay for a volt meter.
I have the primary battery on a keyed power source for it's volt meter, and the secondary battery/volt meter is on the switch that turns on all the accessories connected to the second battery.That is how it I have. If it's light enough when I get in from work today I will take a quick video and maybe someone will notice something.
I think you do if you don't want the meters to stay on. It's not the biggest deal, but like all the other blue LED that shine all the time at night in the house, it kind of annoys me, lol
Maybe at lunch today I will wire up some straight leads to test relays outside of the plug.
Are you running a second fuse box? If so, connect the Aux side of VM to fuse box and main side to your switched 12 volt supply. Unless your second fuse box is wired up directly to second battery where it works without the key on. If so, wire in the relay between the fuse box and Aux side of VM. Pin 30 to fuse box. Pin 87 to Aux side of VM. Pin 85 to ground and pin 86 to switched 12 volts. AKA ignition.Thanks in advance for the help. I have tried searching but can find the answer.
I have the Tru Dual battery w/ dual VM that I got from club store. I am not great with wiring but not completely lost.
I have gotten everything wired up and I can't get the VM to work when plugged into relay. I can straight wire it to ground and it works. I have power coming to relay from the accessory key on wire- test with meter across to ground wires, 12+volts. Have check everything but don't know how to test the relay itself. The isolator appears to be working- LED comes on, volts same at both batteries.
Any thoughts?
Thanks again,Mickey
I wired my dual volt meter up as per the instructions and it would not work. So, I moved the ground wires directly to the batteries and share the same female crimp connector at the voltmeter. The main battery wire from the voltmeter is connected directly to the main battery and the auxiliary wire is s connected directly to the second battery. I installed a $5 dollar momentary interrupter switch on the negative/ground side so it wouldn't stay on all the time. I don't have it going to a relay. Problem solved.Thanks in advance for the help.
