Hi my name is***** to Just Answer ! I will be assisting you.

Ask Your Own Boat Question

I have seen installations like this where black starter cable is used in place of red cable. This is all good in practicality, but in these types of installations they should really be using LONG red heat shrink on the cable ends to identify that it's a positive lead, hence prevent any confusion.

If you wish, remove the battery switch, make sure the middle lead is COMMON and trace the lead back to the engine's + on the starter solenoid.

You should find it is rigged properly, BUT if they have used the only (black) colour lead they had to do the job. PLEASE let me know if you have any START or accessory issues so that we can investigate further. If there are any start issues, don't hesitate to pop the cover and inspect fuses after consulting your operators manual.

Regards,

Matt
