Strange wiring problem, I need help guys!!

ALright, so when I bought my 79 cj5 the only problem with it other than bearing and axles and rust was that there was a short in the turn signals so they had been unplugged. The PO thought that the short laid within the switch so that gave me a starting point, I bought a new(ish) turn signal switch and replaced the old one, when I plugged it in and tried the signals only the right front worked! Before I went to town to pick up new bulbs for the three that did not work I turned my head lights on and noticed that my left (drivers ) side parking lamp no longer worked, so i went and got new bulbs and still nothing in the right parking lamp, I replaced the socket, and I am still not getting any juice to the right front parking lamp, where as I was before I installed the new turn signal switch!!! So now I have no idea what could have happend or where to start, any advice? thanks: Nank


Edit: Sorry guys I meant the left front parking lamp not the right

Check the ground on the actual light.

You have a voltmeter? You should invest in one and see where the disconnect is. If you are getting voltage to the light then just try swaping a bulb from the other parking light and see if it lights up.

There's a good chance the grounds are bad though FYI> Also check the connections on the back of the gauge cluster.

Sounds like a mouse chewed your wires up. If all the grounds are good I would start tracing wires.

You can get bad grounds, worn out light fittings, chewed cables, fried relays etc. As you have now discovered just swapping parts does not necessarily fix an electrical issue. However do not be docuraged, those parts would have broken at some time anyway.

The only way to get it to work is to be methodical and find where you have voltage and where you have continuity.

I would start at the light fittings and look for voltage. Then go back to the relays then the switch and also test the cables in between for continuity once you have stablished how far back in the circuit you have voltage .

You will need a test light and a wiring diagram and be VERY methodical. A meter is useful but with a $5 test light and a longish lead you can get these circuits tested.

Never looked at chiltons, if it tells you wire color it should help plenty.

Sorry to highjack!

Bagus, so you're saying you can test voltage and continuity with just the screwdriver type test light ?

Try this one. When I rewired I found it to be a life saver compared to Chiltons.

For the actual 1979 diagram, just change the year in the link.
