My 77 Chevy c30 has no power. Jumped started it and drove it home. I turned it off then tried to restart it. No power no lights. nothing. Battery is good. An u help will be appreciated.

If the battery is good you will need to follow flow. Test light is the easiest to use. First hook light to ground and touch pos terminal,lights good next touch pos battery cable end, lights good. Next follow pos cable to starter pos terminal,lights good. Next hook test light to bat pos teminal,touch neg terminal,lights good. Then touch engine block, lights good ground. Next move test light clamp back to ground/neg side and touch alt pos terminal,lights good.if all that tests good, if all good move inside and check for power at ign switch pos term if at any time you dont find power you have wiring issue that needs to be addressed. Let me know what you find. Russ

How do u wire I'n a 1972 ford f100custom truck

Sorry iam a thick brit having problems with your spelling which as we all know we cannot spell in the UK or pronounce aluminium or tomatoes so the man to ask is emmisionwiz as hes a ford dealer fitter with enough years under his belt to know exactly what you need to know ,so try a direct question ,but for this year with a seperate regulator why not try a alternator off a later model with a built in regulator ,as for the starter motor then a wire from the contact switch on the back of the key switch that has power when the key is turned to the start position and this wire goes to the small terminal on the starter motor .I do not the facility of a fancy pen thing attached to my computer that i can draw a quick pic for you .

My negative and ground wire was replaced by me on a 94 Ford Tempo, Once replaced the ground wire was not hooked up right. I finally got the ground to work but now my starter is acting up. Sometimes the car...

I would double check all battery connections both pos and neg. If you are consistently able to get it start by tapping on the starter it is likely stuck / dirty brushes. I would replace the starter. If the car gives one good click when you try to start that is the starter solenoid allowing power to the starter but it sounds like your starter may be pooched.
Make sure you return your old unit to the parts store for your core credit.

Take care.

I have a 1996 ford crown victoria and it won't start...the battery is new....but when i turn the key the lights go dim

You will ned a new starter, the windings have shorted and it just draws a lot of current but doesn't spin.

1989 Ford F150 5.0 Auto 2wd. Was Driving in the city and all of a sudden the truck started stumbling lost all power and turned off. Got her towed home noticed the ground to battery was cracked replaced...

If the positive cable is on the wrong side, yes no power. The positive must be on the up side of the solenoid along with the other wires (except your start wire which goes on the small post). The cable going to the starter hooks on the down side. The ground goes to a ground (usually to the motor).

Fuel gauge stuck on full

pos lead is used to measure ground...that means that the power goes through the fuel level sending unit and the ground lowers the power out from the unit....I would replace the fuel level sending unit.

Wiring for a 1993 ford f150 starter

not correct
the negative wire should be attached under the head of a mounting bolt for the starter
the circuit is that the power goes into the positive terminal ( big terminal) through the solenoid when activated out the second big terminal through the fields and armature to ground
the power to activate the solenoid is either from a power wire from the ignition switch to a small terminal on the solenoid through the windings to ground that activates the solenoid and closes a set of contacts in the solenoid to allow the power across the 2 big terminals
