Help Needed with multiple electrical problems

[AChev]

Well where to start, well I have a 1973 240Z. When I first got the car the running lights and dash lights did not work. I put in a new fuse and they worked but it heated up and blew (on right column third fuse down). So I did a vinegar cleaning and all is well there. Although, I re-hooked up the battery and I went to turn on the car. The car cranked and almost started twice, and then after now after that the cra barely cranks at all it just cranks for 1 second or so and stops, with successive tries it barely makes any noise at all.

I also have problems with the low beam lights. When the low beams are turned on all dash and running lights turn on except for low beams. When I switch to high beams the lights turn on, but not on low. Also when the dash lights are turned on the left blinker light is constantly on. The blinkers do not work when the car is at rest, but while driving the car the blinkers work.

So there is all my electrical problems laid out. If anybody could give me a hand in solving my problems, that would be wonderful. Thanks All

Sounds like the car is possessed...

Start by checking the earth from the battery. By this, I mean cleaning the terminals thoroughly. That should solve the starting problem.

Indicator lights can be caused by using the incorrect globe. By this I mean a single filliment has been used in place of a twin filliment, or vicaversa.

Start with the earthing problems first and progress from there...

Good Luck

Thanks for the quick reply MOM but the battery is very new and the terminals are already clean, thanks for the suggestion anyway

HMM my two cents are double check your ground wire as well as your positive connection on the starter< both must be very clean >, if you haven't already while the battery is disconnected remove the fuse box clean the back and all termals and spray with a sealer , I had very simliar problems and solved them by replacing my fuse box. If the battery isn't run down < would hurt to charge it a bit > check to be sure the starter is engaging , but if the battery is good and the starter is good other than connections not being clean either it should turn over or not when the key is turned , good luck

Since it all happened after you vinegarized the fuse box, I'm thinking that you must have loosened or broken a connction related to the fusebox. Did you unplug the fusebox when you cleaned it? Recheck the fusebox connector(s).

Well when cleaned the fuse box I did not clean the whole box. I disconnected it and just vinegarized the fuse clip that needed it. I am almost positive I rehooked it up correctly. Well thanks tomohawk and seerex, I hope your solutions work

*Luckily the starter problem was just the battery, it was recharged and all is good with the starting, now I just gotta fix the lights and signal*
