Re: Oil pressure sending unit?????
Hey Jeepgod, look at those accessory voltage points with an Ohm meter (of course with the battery removed)... If I remember correctly these points are affected by the turning of the key from and to varied modes. As example if Franks fuel pump were connected to the ACC circuit, when the ignition key moves from START to RUN mode there would be a loss of voltage to the pump during the key movement. This could cause problems... and besides, do you really want the fuel pump to be pumping fuel when the engine is off and you only want auxilary circuits operational?
