Boat Engine Wiring

[joe_zef87]

Hi there,

I am looking for some guidance on wiring between the alternator/solonoid/starter please.

The Loom has cables labelled-

SUPPLY (Red)
??AT (Brown - large gauge) Took a photo and annoyingly i cant see what the label says
Tacho (red/white)
Negative (Black)
Start (Blue)
IGN W/LT (Pink)

Oil Alarm (green/Red)
Oil (Brown)
Temp (Green)
Purple/white???

The Alternator is labelled B+. B-, W, D. and the starter solenoid has 2 spade connectors at the bottom, which i thought the Supply and Start would go, although not sure which is which. Along with the Negative to the Batterys (connected in photo). I have the Main COM Positive connected from the main switch into the side of the starter

.

Any guidance would be appreciated.

thanks

Start a new thread and provide more detail on exactly what happened. And check all of your fuses.
