Thanks Bt.. do you think connecting each Battery Neg to a master Buss Bar would work? or is that not helpful (was thinking it might keep things uncluttered) Thanks
Just a final note - replaced pump; primed correctly :); Temp control was wired correctly. - works 4.0 now. Has been running in heat and cool mode for well over two weeks. thanks for help
Hey Jeff - sorry I should have mentioned the total result :)
I first changed just the sensor - it did fix the gauge reading but not the overheat. i changed the thermostat, Barnacle Bustered the heat exchanger, and changed the raw water pimp. end result was gauge works and the overheat is NO...
it might thanks. im willing to run the cables the way I think it should but i sure would like a schematic
This is what is presently wired - its really strange :)
Hi Our 300 has twin 5.7 and QS 4.0 with three batteries. does anyone have a wiring schematic on where each positive and negative of the batteries are connected. this boat has had someone change the wiring and I would like to try and get it back to the factory design
Thanks
Just a follow up - replaced both engine sending units and over temp sending units. of course the ones the parts manuals have now is different from what was installed :) thanks for the help
