4.3 Volvo Penta Fuel Pump not working , need help finding Diode please...

[ram750]

Hi Guys ,

I followed a thread found on here yesterday and managed to isolate my issue and get my friends boat running. The problem is that the relay for the electric fuel pump is not coming on. The power from the alternator to activate the relays winding is not giving anything on the relay side. The alternator is putting 12-13v from the green wire so at this point I can only imagine its the diode between ....

thread followed to isolate my problem...

Thanks Don BTW !

In the mean time I rigged up a little jumper with a switch to allow him to start the pump manually by jumping current at the relays socket.

This one has a lot more amperage than you will ever need, but will work perfectly. http://www.radioshack.com/product/index.jsp?productId=2062591

Do you know where the o.e one is located ? just so I can try and pin point if the wire is broken or something ?

The problem is that @ the alternator I do have 13 some volts but not at the relay ... So I can only figure that the wire or the diode is baked..

In the green wire someplace, where exactly is impossible to say. Just follow the wire till you find it.

It run's right into a bigger harness as soon as it leaves the Alternator ... I would have to cut and open the tape everywhere to find ... Might just run another wire with a new diode in it , do you know if this feeds anything else ?

Thanks
