Have you always owned the car ? sounds like it could be someone had a system in it or something .. I believe that extra wire should be clipped or unhooked so it wont short out on something ...

What would cause a 2001 chevy cavalier has to be started touching wires on the starter?


There are 2 wires to thr Starter. A thick cable which comes directly from the attery and a thin cable which comes from the ignition switch. it would appear from your description that one of these is either loose, dirty or has a bad solder joint. Establish which wire you are touching that makes it work, then you might have to replace the terminal on the end.

Alternator wiring harness


An alternator can run on two wires, the thick wire is the supply to charge the battery, direct to positive, via fuse box or starter supply. The thin wire possibly blue on Fords, is the energiser wire from the dash charge light, without this connected the alternator will not charge. If on the new pigtail two wires are thick (30amp) you can ignore one, some vehicles double up on the charge supply wire.

Hard start and smoke after replacing starter


1.Probably the battery to starter thick wire is loose, jointed, under sized (too thin to hold the heavy starter current) or shorted to ground.
2. Main ground wire from battery to engine is loose or aged.
3. Improper connection between the battery and chassis ground.
4. Starter motor defective.

Have a 1994 Dodge Ram 1500 4x4 1500 with wiring problems. The original problem was a brake light out on the drivers side. I changed the tail light plugs. With head lights off I had brake lights with head...


Your truck may have had the factory trailer tow package, but that did not come with a wiring connector in that year. There should be a wire harness under the rear of the truck near the center of the bumper with 7 wires of the following colors/characteristics -

Red/Orange - +12V Battery (Thick Wire) From fuse #8 (40A)
Black/Orange - Tail Markers (Thick Wire)
Light Blue - Trailer Brakes (Thick Wire)
Violet/Black - Backup Lights (Thin Wire)
Dark Green/Red - Left Stop/Turn - (Thin Wire)
Brown/Red - Right Stop/Turn - (Thin Wire)
Black - Ground - (Thick Wire)



Under the dash, the brake controller wiring should be -

Red/Orange - +12V Battery (Thick Wire) From fuse #8 (40A)
Black/Orange - Ground - (Thick Wire)
Light Blue - Trailer Brakes (Thick Wire)
White/Tan - Brake Light sense - (Thin Wire)

Hope this helps.

get 2 lengths of thick wire cut the wires after you find the positive wire,it usually runs from a cluster on most cars, ground will be bolted/screwed whatever to the frame.

Car won't start. Changed starter. Still wont start. This starter can not be checked when it is off the car.


Hi there?
Check that the battery is charged, you can do this by turning the lights on and see if they are bright as narmal.
There are 2 wires going to the starter motor, thick and thin wire. The thick wire is connected straight to the positive terminal of the battery. The thin wire is connected to the relay which is operated by the key. You can power the starter motor by powering up the terminal that the thin wire goes to. Make sure that the thick wire has positive loltage from the battery.

I just bought a 2002 grand am gt and the back speakers are disconnected. They are the factory speakers. There are 2 thick wires in the trunk and there are thin wires hanging from the speakers with splits...


This sounds like the previous owner installed an after market audio system. The short answer is "No do not hook the split wire ends to the thick wires. I suspect that the thick wires are power and ground for an amp and they used the rear speaker wires, split ends, as the audio input to the amp which in turn drove whatever set up they used.
With that said, it sounds like they cut the connectors off of the speaker wires and put the splits on them to wire in the amp. The splits are probably very close to being able to plug into the speakers. that is a good sign that I am right. If this is the case, you can have a tech wire the speakers back in. Also, make sure that there is no live power to the "thick" wires as that is unsafe. At least get some tape over any exposed ends and tuck the wires in a safe location.
I would need pics to comment further.

Have a 2001 fiat punto..was running then just cut out...got spark no fuel pressure ...have located the fuel pump....4 wires going to pump...on 1 of the wires on ignition its 12 volts but when you crank it...


Have you had the fuel pump output pressure checked....Sounds as if it could be defective.....Pressure should be above 3 .6 bar Or maybe check your battery condition, that may be the problem, but more likely the pump....

93 honda prelude dohc vtec engine will not can be push started


Sounds like you accidently pulled the thin wire from you starter motor. Look at the connections at the end of the solenoid, mounted on starter motor.The thick red wire is Battery + next to that connection is a smaller male push- on terminal, locate loose wire (thin) in the same area and reconnect to male push-on terminal on solenoid or check if earth cable between body/battery to engine wasnt removed in the process.Also some vehicles you have to engage the clutch before starting, check for a switch located on clutch pedal where master cylinder connects to clutch pedal (Is clutch switch mounted and wiring connected?)

you should only have 3 wires going to the starter there will be a large black wire possably with a red end, a thiner red wire and a thinner purple wire

the thin purple wire is the trigger wire and goes on the small post on the starter solenoid. \
the thin red and thick black/red will get tied in together on the larger post on the starter solenoid
