Sluggish on a quad core Samsung Tab S running Android Lollipop - not recommended.

So is the cold return to the engine at the top of the skin tank? If so where is the hot flow into the skin tank connected and what type of skin tank do you have?


What other symptoms of overheating do you have apart from the temperature gauge and have you used an infra-red thermometer on the to confirm the gauge reading?


Not sure if this was a trick question to catch out the OP. If not surely the cold outlet from skin tank should be at the lowest point.


Agree a cheap IR/laser thermometer would help in sourcing the problem and like you suspect the gauge and/or sensor as suggested in post #3

In Topic: Odd behavior on battery negative

Today I have individually disconnected each circuit in turn...I have three lighting circuits, all run in 2.5mm tri rated, these three circuits have fourteen LED's in total running on them and all three negatives are causing the negative path!!..any ideas other than binning the LED's!!..they were bought from Midland Chandlers at £12ish each..cheers


Totally agree with Paul above. I think you need to isolate all of the DC distribution circuits from the common negative bus, then add them back one at a time until the hull path is revealed. Worth checking that the negative bus itself is completely isolated from the hull of course.


Whilst I wouldn't expect this, are any of the LED's mountings in contact with the hull? If so remove from location, even if just temporarily and check again.


Beware that secondary path issues can very easily be mis-interpreted when fault finding and sometimes come from the most unlikely places.

In Topic: How come my generator still runs when the fuel pump doesn't?

No the lift pump isn't working at all.
At the moment it's about level.


I think you have answered the query yourself then. There will be some suction as the injection pump operates, but it will be only a matter of time before fuel starvation cuts engine. Likely then you may then have to bleed the injection system.

Either that or the lift pump is getting a negative return through its casing to engine block and hence battery negative.
