12VDC output of the alternator spliced to a wire that runs to the voltage regulator.

Straight into the regulator with another output wire, or is it in parallel with the output of the alternator?

This setup was done before I bought the MH, so I don't know what was done in terms of wiring. I hope to find that out in time...

Anywho, I have a big switch in front of the heater core that switches from battery 1, battery 2, Both or None.

The isolator is on the drivers side, on some sort of homemade bracket.

There is a regular car battery in the center, and the second battery was put behind and below the drivers seat, and is a deep cycle monster which is or has leaked and has corroded some of the metal. In an earlier post I asked about changing it...

This setup seems to work fine for me.

There are 2 wires that go into the regulator there is one that attaches to the 12 volt block on top of the frame near the alternator the other goes into a wire loom. The output from the alternator is also attached to the 12 volt block. So I guess that makes it parallel??? I do not know where the other wire ends up.

There should be another heavy wire coming off the terminal block that eventually goes to the battery. It probably goes to the lug on the solenoid and charges the battery like that. You need to get this out of the circuit and run a wire straight to the input of the isolator from the block.

I have the regulator sense wire connected to the output side of the isolator. HWen I run the engine I have a 17 volt reading at the dash meter for the engine battery, I did not run it long enough to check the coach battery.

I am going to move the regulator sense wire back to the output side of the alternator to see if I get a more normal output.

There is a fairly substantial drop across the isolator because of the diodes. If you move it the voltage should drop.

The voltage after moving the regulator feed is now in line with what I expected to see on the dash gauge.

Now we will see if it works like it is supposed to this weekend. I also spent time replacing the dead house battery, and stripping tie wraps and looming the wires that run all over the front of the engine compartment. I have to get it neat before Mystic Springs because you are all going to want to see my shiney new carb.

BTW the carb came and it was the wrong one. I musta fat fingered the order form on line. I am returning it for the same CFM, but with the reccomended electric choke. So the Carb project has to wait until the week of the 20th, oh well, jsu more time to do dress up.......
