altenator help needed
hi all
can anyone help please
i have been fitting fuel sender/gauge, oil pressure sender/gauge and temp sender/gauge and at each stage checked that all was ok.
BUT after fitting the last connection, (the oil pressure low warning light), switched on the ignition to check and the ignition light dimmed and went
off and will not now come on.
the connection from the alternator to the ignition light are ok.
SO please does anyone have any idears.

if you undo the last connection does the light work then?

hi again
i have disconnected the pressure sender(which is new) and the light, then checked the voltage from the alternator which read very low about 2 volts
i hate to admit to myself it might be the alternator

2 volts from alternator???
output of alternator connects to battery so unless your battery is totally knackered, then that is not pissible.
the other connector, assuming Lucas alternator - goes to bulb and other end end to 12 V of battery - this is the small current needed to help the
alternator self-excite.
When off, this should be 0 V and bulb lights, it still should light up even if it is 2 V.
when laternator is running and charging, the connector goes to 12 V and since there is not voltage drop acorss the bulb, no current flows through it
hence the bulb does not light up.
