can any one tell me how the the sender works? is it mechanical or vaccum operated. are they easy to replace?
i was sorting out the wires trying to clean up the spagetti arrangment and try to fix the alternator surges, have got that under control but now theres no reading on the oil gauge.
the most conventional sender unit is electric basically has 1 wire and earths thru the engine to chassis there are also capillery gauges which has an actual oil line to the bak of the the gauge, these are probably more accurate but i dont like the idea of having an oil pressure line in the cabin or pointing at the windscreen. Have u reconnected the correct wire to the oil sender, u may have to retrace ur work, if its a mechanical(capillery) sender u may have hinked the hose when tidying up the wiring at the firewall. Gud Luck
mine has one terminal and no oil lines, it's electrical.
just bought a new one and still no result.
have tried to see if the fault was in the wiring loom plug thats
fixed to the firewall, i connected a wire from the sender to the cab side of the plug to bypass the plug and still nothing.
i'm guessing the fault is between the plug and the gauge.
thing is i didnt work near that plug today when i was re arranging wires or go near the sender??
is there a way i can test to make sure that the sender is working, ie test lamp or voltage?
