i noticed that a wire going to the coil sends a signal to the light - is this correct or could this be my problem causing the flickering?? if i disconnect this wire the light goes out. jim

If the readings are OK, then replace the sender. Otherwise you may need some engine work. |

Oil pressure light does not attach to the coil. It goes to a wire that will come out of the harness near the center of the case on the passenger side

i do not have my haynes with me and still have lots to learn - but my engine is a GA001xxx and off the harness that goes near the coil have a black wire that goes to the coil and a green/brown wire that (when plugged onto my coil) makes me oil pressure dash light blink wildly. if not to coil - where does this connect to. note: my car is a 1975 wiht a 1973/74 engine. thanks !!!

It should be a green and red, I think, wire (old wire= red may look brown) it
should connect to the oil preasure switch. You will find it behind the dizzy (torwards rear of car) thru a hole in the sheet metal, only a few inches from your dizzy IIRC. |

(actually, most coils do have oil in them .... shake one if you have one out.... unless it is epoxy filled for high vibration applications)

About 10,000 volts PSI. (IMG:style_emoticons/default/lol2.gif) The higher your RPMs the more it would flicker eh? |
