I need a wiring diagram for a 1974 MG Midget

I have a 1974 MG Midget which recently developed a short in the small brown wire connecting to the alternator and burned quite a few wires in the harness. I believe I have fixed that problem, however; I only have earlier diagrams which do not show all of the brown wires in my car,nor do they show the white/brown wire which I believe connects to the solenoid. two heavy gauge brown wires are connected to the positive terminal of the solenoid as well as a smaller guage brown wire. There is also a thinner guage brown/yellow wire. All of these thick and thin brown wires lead from the positive termal of the solenoid to the alternator. This must be wrong as they are hot all the time. Also, the white/black lead form the distributor attaches to the negative side of the coil and then continues on into the harness. My most recent diagram shows only two brown wires from the positve terminal of the solenoid and a white/red wire from the distributor to the neg. side of the coil. I would appreciate any help as to what I am obviously doing wrong or a free source for the correct wiring diagram would be great! Thanks for any help, Tom in Gilbert, S.C.

SOURCE: 88 s10 wiring problem

if you have a 4.3 liter the wire from the positive post on the battery should go to starter and to the post with 10mm nut on the back of the alternator with a 2nd wire that goes to your ignition coil. ignition coil wire should have a fusible link in the line.

I have the same model year as yours, but that does not really matter. If you go to the back of your Haynes manual, the wiring color codes are spelled out for you specific to your car, It is possible that a new or rebuilt starter can be stuck (clearances on starter gear/and shaft) or that you somehow bolted it in slightly askew and it is stuck or cannot move properly. Spot check the ring gear teeth by looking through the starter hole to see if they are o.k. and that the gear on the starter seems correct.  Also, look around and check and make sure the ground strap is good (motor to body) or any ground for that matter Sometimes, if a motor or starter motor is in a locked rotor condition this will cause a heat rise. It might be a good idea to remove it and energize it with jumper cables from the battery-- (a bench test) to verify actuation. (spin)  Then wipe the grease of the leads (so you can read your color code) and carefully connect them to the terminals as the wiring diagram tells you in the Haynes manual.

Wire diagram for chevy 3500 van

When you say charging,do you mean amp reading or volt reading?Amps should rise when first started then drop.Volts should stay close to constant.The small wire going to the alternator to power the regulator in the alternator is just switched power.If the volts fall under 14 after ten minutes you may need to try a replacement alternator.

I need help with wire connections for power window switch on olds ciera front passenger door.what color wire connects it to master switch?

In the diagram, the brown wire is voltage for power windows. Goes hot when you turn on the key. Voltage comes from the power window circuit breaker. The black wires in the middle of diagram are ground. Use a testlite to check voltage on brown wire, key on. If the brown wire has voltage, to check the black wire for ground, use a testlite between brown wire and black wire. If lite comes on, you have voltage and ground.

I need to know how the alternator is wired to the vehicle in a 1986 pontiac Fiero. mostly the small plug not the main red power. Were do the two small gray wires connect

Per the shop manual those wires are brown and red. So pull back the black wire cover and check the color of those wires. On the V-6 the small red wire connect to terminal 2 , small brown wire connect to terminal 1. On the I-4 the small red wire connect to terminal S , small brown wire connect to terminal L
