Instrument panel query

[Colin K]

Hello,
Wondered if anyone had come across this one? Just fitted new "second hand" engine and as its 12v instead of 24v have used the panel that came with it. All works fantastic but it has two warning lights, One for the ignition/alternator which is red and goes off when the engine starts all clear. The second one is green and marked Temp. The wires that were connected to it are simply pos and neg hence it stays on all the time ( I've disconnected it at the moment ) My wiring diagram from the Sea Panther book "deluxe wiring" shows this light as being an oil pressure warning light so thats no real help. I would have thought that if it is a temperature warning then there would be an extra sensor?. If I am being a bit stupid or there is no easy fix then I am happy to keep my eye on the temperature gauge like a normal person! But wondered if anyone has come across this or has a later model Watermota Sea Panther and so can shed any light?

Cheers, Colin.

It's very difficult to be specific with this older stuff as many have been modified or use non-standard parts over the years.

I have two senders on my older Watermota engine. One's a temperature sender & that's a linear sender. The other is an oil pressure sender & that's just a switch. You can get switch types for both temp & oil pressure. They come in two types: insulated & non insulated. The non-insulated ones only have one wire connection. So, you have a wire from 12V to the light & another from the other side of the light to the sender. The current returns through the engine block to battery -ve. The insulated types have a second wire connection that returns current to battery -ve without going through the block.

There's quite a bit of info on senders & connection on the ASAP supplies web site.

Gosh thanks for the info, I will need to chew on that one ! My temp sender has two terminals, think they both go to the temp gauge which works grand.Neither of the terminals are earth checked that with a continuity tester. Back on board Thursday so onwards.
Thanks again, Cheers. Colin.
