Hi

I wonder if anyone can please help? I have a red, amber and blue ignition light on my dashboard for each engine. Could someone please tell me what each is likely related to?

TIA

Red is commonly alternator charging, the other 2 are likely to be water temperature and oil pressure. They should all go out when the engine is running. Only sure way of telling which is which is to trace the wires to the senders on the engines.

If you have just bought the boat, ask the seller/previous owner. What engines?
Red could be the charge, alternator light. The other 2, oil and water?
The oil one will go out with the ignition on and the engine stopped if you pull off the wire at the sender.

Hi
After market installation. Just three lights above each ignition key?
I'd expect the "no-charge" warning light and the "low oil pressure" light to come on when the "ignition" is switched on and to go out when the engine is running, but I'd not expect a high temperature warning light to come on expect when the engine overheats, although I am aware that many Volvo Penta panels are designed so that the high temperature light also comes on at first switch on.
