sub tank light stays on but switch works and pump works, the little green light on the switch even comes on.
Have done the earth thing and reset the module but light still stays on.
Have put in two larger tanks /140lt main and 85lt rear.
This is when problem started.

cheers.

Earthing?

Edit... Doh, cant be that should read more closely instead of skimming...

Hmmm... curious... must have something to do with the mod tho, you used the original pump etc?

No, used a different pump, but still just has two wires like the old one. Thats on the sub, the main does not have one.

What Mike said X2... that is why I asked. Its really odd that the system is working but still with the warning light so it isn't one of the 'normal' things causing it.
