Engine & Thruster Battery Connections C-28

[RichV]

Can anyone send me a picture of the wires connected to the engine and thruster batteries? Because of the zip ties, I don't see how I can get it wrong, but connecting after winter storage, the engine EVC is blank and won't come on/no turnover.

I can not send a picture that would help because I have a C26 and have moved my batteries to a different location. If no one has changed the factory cables all should be marked. Engine battery, Thruster battery, House battery, Positive cable , Negative , and jumpers are all marked. If they are not marked ,simply trace back to the source. Engine battery should have a direct Yellow (Negative) lead to the engine (ground). Red (Positive) from battery to engine battery switch. If you have doubts of battery cable configuration the best way to confirm it is right is to trace the cables to their connection. Having this knowledge my come in handy in the future and possibly resolve your issue now. In doing this you may come across a poor connection ,corrosion or loose cable connection. I would also confirm battery condition fully charge and load test.

(you will likely already have done this) its worth checking the connections are good.
I also sanded the contacts slightly to remove any corrosion and applied a liberal dose of corrosionx when reinstalling.

is there a reset feature on the volvo EVC if it loses power for a long time? I only swapped a battery so it wasnt unplugged for more than a couple of hours.
