new problem

[dockmasterdave]

I posted yesterday about having problems with my norcold 410.
troubleshooting it today, I no longer have 12v to the power board.
I only have 8.8
I replaced the connector on the ground yesterday, all looks clean and tight.
I have 13.6 volts at my main distribution panel. I see one large red wire leaving the panel, and two reds going into the ref 12v power board.
Can't see where they go in between.
Any ideas?

I use fused jumpers to be on the safe side. JMO

Update: Thank you artum smowbird.
I ran a 14 ga jumper wire directly from my main power panel to the ref "power board"
I now have what I had yesterday, 12V at the power board and 12V at the display board.
No lights of any kind.
It appears I have 2 problems.
#1 now only getting 8.8 volts using the factory wiring.
#2 I suspect the power microswitch.
Does anyone know if/how it is safe to bypass the microswitch as a test?

Before you pull anything out, run a new wire from the power board just to the positive point on the fridge and then you will be sure it is the positive feed.

Have you checked from positive to negative right at the fridge board terminals? Then check from positive to a good ground, maybe the side of the A/C box.

Also disconnect from the fridge board and measure the voltage.

Single red from power center runs over below the fridge, then up , out of sight. Outside, behind the fridge two reds and two whites come around a wall and into the ref power board.
Looks like I have to pull the ref out of the cabinet to see what happens to the wires.
Weird that I had 12v yesterday and only 8.8 today.I have 13.6 at the converter. I'll check at the batt terminals.

I'll keep looking. Thanks

Check that the battery is actually charged and that you are not reading a surface charge, a battery may read 13+ and under load be anywhere in the 8 or lower.

The boards need to have a minimum of 10+ volts to operate, not phantom voltages.

Don't know of any quick way......just chase the wires
Did you check the fuse panel.
Could run temp 12wire meantime.
