Starter wont turn

Check the battery charge. Do you hear a click if the battery is good? Maybe Starter solenoid is bad. If the battery is good, and no click. the wire to the Starter solenoid is a bad connection, or wire broken, or trace that wire back to a relay, and from relay to ignition switch terminal may also be bad. A jumper around certain wiring may help isolate the problem.

Bought a used 1983 southwinds motorhome but no batteries. does someone have a wiring diagram for the batteries

no diagrams but the reason for duel 6 volt batteries is for proper distribution of power you can put duel 12 volt in it and it will seem to run fine but over time fueses will get weak and start to pop as well as relays. i hope this information helps. J&D services

1997 chevy cavalier. Is there any way to bypass the ignition switch? The car will turn over with a screwdriver to the starter.

The problem is most likely the starter relay, not the ignition switch. Ignition switches had a high nfailure rate in Cavaliers due to starter current. GM issued a recall and added a starter relay to solve this. The relay will fail periodically, resulting in a much easier and cheaper fix than a new ignition switch. If your Cavalier has the relay, you will find it in the very front of the engine compartment, just left of the battery, fastened to the back side of the radiator crossmember. GM Dealers have the relay for about $30.00.

I have a fisher plow every time i move ther plow control up or side to side the vehicle stalls

If your plow is electric/hydraulic then you will have to introduce a second battery into the system and upgrade your alternator to a heavier one. The good news is that GM has the battery kit, it can be found in any diesel truck in a salvage yard or ordered from the dealer. Upgrade your alternator to at least a 70 amp output. If you have a local battery and electric shop they can upgrade your current alternator for a lot less than buying a new or rebuilt one. Hope this helps.

How and What additional parts are needed to install a second battery into a chevrolet Silverado 2500 HD pick truck?

You need a second battery box and some cables. This is a package you can get at the dealer. The older diesels all came from the factory with a dual battery setup. You could also probably find it at a junk yard. Just check under the hood on any diesel GM truck there. Hope this helps.

Did the new pump come with an upgraded wiring harness? GM had problems with the connector that plugs into the pump assembly on top of the tank. The better brands of pumps come with this upgraded wiring. You might want to check into that.

How do you put a starter solenoid in a 1988 ford f150?

Ford does not put the solenoid on the starter itself, so then it is just a relay, usually on a fender. It will have 4 wires. Two thick ones from the battery and to the starter. And 2 thin ones from ignition switch and to ground.
