Waste system control panel

[Boat boy]

I have a 2001 260DA and I'm having problems with my indicator showing levels and power. There is 12 volts present on my key switch, which goes through the overload to vaccuflush generator pump, which works, but my power indicator light or any level indicator light for waste tank, never illuminates. Has anyone ever had a problem with theirs? Any help would be appreciated...
Thanks

The level indicators not registering is fairly common. There are three level indicators on the holding tank, they get mucked up. Re-seat those and make sure there are no loose connections.... That usually does the trick for me.

yes, but shouldn't the power light be lit, because 12 volts goes right to the indicator when the switch is turned on?

Make sure the "head" is turned on within DC breaker panel... Also, not sure if it lights unless seacock is open on discharge.

Yes, Been Working on mine......issue is there is not a negative 12 DC side on the PC board that is shown...wire # 506 has to be 12dc hot and not sucked down by a wrong 12 neg Dc....some people tied wires 506 and 139 together in the head on the key switch panel. this is not what to do I need layout of the board.... the switches all work.... full/1/2 and Empty...the two blk wires are not negative side. only wire #139 is to be Gnd -12dc...if you tied 506 to 139 it will suck down the 12vdc because its black and it is wrong. we need to find the -12dc on this board in order for it to work.... any help! I will attach image.

here is the schematic for this issue.

My master head breaker has to be on for the waste panel to light up. I had to replace the sender. The old one was not salvageable.

ok been working on mine and found that the Gnd for the display DSP1-2-4 need to be Grounded out at the control station ground Bus....hears what we did to solve....and I hope this will work for everyone.... ground out wire 506 to 139....ground buss.... I will attach a Schematic for everyone to see what to do on your end....GoodLuck and happy Motoring.
