I recently purchased a Seamaster 30 with a Perkins
4.236. The engine
is running fine but the Fuel
and Temprature gauge do not work
I have a very basic understanding of electrics but took a look to see if I could figure out the problem today.
The positive supply to the two gauges that are not working is coming from a terminal on the ignition relay (or at least what appears to be the ignition relay to me). The only other item this terminal is feeding is an LED on the dashboard that also does not work
To see if this was the issue, I connected the fuel
and temprature gauge to the same positive terminal from the ignition that supplies the oil
pressure gauge, rpm
gauge and a second LED on the dashboard, all of which work. When I did this the gauges kicked into action.
My question is, is there any issue with powering all of the gauges from the same terminal on the ignition and avoiding the terminal on the relay? Or is there a specific reason the terminal on the relay is used for the fuel and temprature gauge?
Also, what should the LED that is fed from the relay indicate?
Apologies if my explanation isn't very clear. This is my first boat
and I'm a complete novice!
Any help would be very much appreciated!
