Ok so my coach is plugged in batteries (test 13.3) are fully charged. All fuses read 13.2 on my tester in and out.
The red wire for the relay on firewall the one in the back is 13.2 all the time. The red one in the middle is 13.2 when key is on. Is the wires on the right post on the relay??? I replaced it before and want to make sure I have that right.
The wires for the switch. The red one reads 2.3. I would think that should be 13.3 or at least 12.0. The rest read nothing.
So when I turn the key on the red wire at the switch goes down to .04. So I think the relay is doing its job.
When the switch is pushed the one wire reads 2.3 then the opposite when the switch is the other direction.
It seems to me that the wires from switch to the motor are fine.
I think the problem is at the switch. it doesn't have 12volts.
Would the red wire from the switch be the wire hooked up the relay (on the firewall). That gets power when the is off???
Also seems to confirm there is no control box or board I think.
Before I didn't realize that the colors do match up from switch to motor. Brown and blue.
