Default no backup lights or turn signals

I noticed that when I went out tonight I only had a high beam and no low beam. Plus no backup light either. I turned the car around like right and headed home. I read the 62 manual. The turn signals could be a bad fuse. But when I lifted the hood I noticed that one of the two wires was off the stoplight sender. I reattached that wire still nothing. The two wires coming from the sender on top of the master cylinder one was completely off. Is one of these wires a hot wire and the other is a ground wire. With one of these wires off for maybe a day No I take that back I had my turn signals earlier today I recall. So I would say the wire was off about four hours. With that being said Would you say something got shorted out or maybe blew a fuse in the process. I will pull the turn signal fuse tomorrow. I do have lights in the rear but no backup lights plus no low beam to the front. Is the sender the culprit. Please advise if anyone can. Thank You Larry. Ps I haave a high beam but no backup lights or turn signals.

First of all, NONE of those wires go to ground; the light bulbs do. If you put the Stop Switch wires together your stop lights should work. If not, check the fuse.

You are right about one wire being 'hot' all the time. If that wire came off and touched ground, it probably blew a fuse. I heard NO report about whether you stop lights work or not. It is impossible for them to work with the power wire off.

Replace all wires that are off, make sure your connections are tight and then replace the bad fuses. - Dave

Default Hi Dave

Checked the fuses and they appear good. Tighten the two wires on the stop light switch and low and behold I now have the backup up lights. Now for a ohms law question. I still don't have a low beam on the front headlights. I have a high beam but no low beam. I pulled the hi beam low beam on the floor board out.As looking at the switch marking it has on one brass fitting the word Fomoco and on the plastic that the three prongs our attached too It reads Little Fuse written on it. One of the three prongs to be loose. Now hooking up my DVM to the top prong Which is the negative lead to that With the high beam engaged I get on each of the two prongs infinite readings . Now when I engage the buttom again I get o ohms on one of the terminals and the one across from it reads infinite. Would that right there tell me I have a bad switch or not. Even shot some electronic cleaning inside of the male three prong plug but to no availe. Please advise. Thank You as Always. Larry

Larry,

If your ohmmeter has an audible signal use that instead of the readout. With the switch in one position you should have a beep when you connect to two of the terminals. With the switch pushed on you should have a beep on the other terminal. The switch is readily available at most local auto stores and is not very expensive. You can take it apart and clean it but I'd just recommend replacing it.

John

Larry, NONE of these go to ground, the light bulbs do. If you touch one to ground with he headlight switch pulled out, you will short the circuit (and bad things will happen).

The High/Low Beam Switch is JUST LIKE a household 3-way switch; one connection is fed from the headlight switch and in turn, it feeds either the LOW beams or the HIGH beams.

Push the headlight switch in (no power). On your High/Low Beam Switch, find the one terminal that is fed from the headlight switch and connect it to your OHM meter, your readings to the other two terminals should show; zero ohms (a continuous path) and to the other terminal you should read 'infinity' (an open circuit). When you press the switch, your results should be opposite.

More importantly, I want to know why all these electrical connections are loose! They should be VERY tight. All of them. Wires that fall off aren't going to make it in a vibrating car.

So again... Replace all wires that are off, make sure your connections are tight and then replace the bad fuses. - Dave

Default hello John.

Replaced the switch. Its not the switch. Still no low beam on the front headlights. The main ground wire was somewhat loose on the engine block so I retightened that.Both low beams on each head light couldn't have burned out at the same time. Later today I will take off the front facia from the head lights and look at the wiring and go from there I don't no what else could be done from the last point about the wiring that goes into the headlight. Any other suggestions what to look for. Thanks for your interest. Larry

Larry, your meter also checks for voltage. There was no reason to buy a new switch when the meter will indicate whether power is passing or not.

I once had a Pinto that burned both headlights out at the same time. I refused to believe it but the volt meter never lies.

Larry,

Did you test the old switch as I suggested. You would have found out that way that it was not the switch. A lot of times the trouble is a bad ground if both go out at the same time although I've also had two bulbs burn out. I would check all the connectors near the headlights. Sometimes they get corroded and need to be unplugged and cleaned.

John

Default looking at the sockets tomorrow

I will tomorrow John pull the socket off the headlights. Look at the wiring for frays spray some electronic cleaning fluid in the sockets. I switch out the old headlights awhile ago for the Halogen ones. Nothing ever comes easy for me with this car. Thanks again for staying with me on this appreciate it. Larry
