Charging diagram

Unless it is ancient or a smart-charging system a diagram is hardly needed.
For years only two wires have been fitted to alternators; a thick one traveling to the battery by a direct route and a thin wire coming directly from the earthy side of the ignition or battery light.

There have been few variations. One notable one was AC-Delco machines older machines used an extra wire to sense the voltage supplied to somewhere behind the dash.

The more recent smart charge systems have an extra clump of wires connecting it to an ECU which controls the battery light and stops the unit charging during acceleration to improve economy.

When charging my a/c do i use the bigger line or the smaller line? 2008 malibu.

it can be charged in either or both depending on what you are using to charge it. if you have a small can from a part store, then you charge the low side.(it should only fit one port). if using a machine it can be done thru either or both.

Battery keeps draining

Take the Navigator to an Autozone, Advance, or Oreilys for a FREE alternator test. Could be bad Diodes. Diodes keep the current from reversing when the alternator is off.

There are analyzing machines at the Dealer. These machines can connect to the 100 (approximate)pin connectors and test 100 circuits at a time.

The other option is to test 1 circuit at a time. Often Relays stay connected in error when their contacts melt together. The appliances would still work because they are connected, but would drain the battery because they would never shut off.

Many people do not understand Relay distribution. Because of the large electrical demands, power distribution is separated by series of Relays. Both Positive and Negative wires are used. As long as 1 charge is disconnected, current will not flow. This complicates testing because the vehicle chassis is a Negative charge and bare wires can ground and absorb a Negative charge to a wire which was intended to be off or void of any charge at all. Shorting "out" is a term when 2 different charges mix. But a Neutral wire means devoid of any charge at all.

Check Charging System/told not the alternator

Check your battery connections - where the cables connect to the battery posts AND where the cables connect to the starter/main power feed and where the ground cable connects to the engine and/or frame. A poor or corroded connection can cause intermittent problems and poor charging performance.

Lost all power in mitisubi gallant

If your machine ran out of battery power from not charging and the car will run with a fresh or charged battery, then check the alternator fuse on the positive battery clamp. If it is blown then even though your charging system is in perfect working order, your battery will go dead and your car will die in the middle of the road. If blown by the fuse at a dealer, replace it and charge your battery.

Changed battery and alternators, but after a few min, alternator putting out 13.5 volts and battery is not being charged. In addittion car dies on iidel.

13.5 volts is not an unreasonable voltage. How do you know it's not taking a charge with the new alternator and new battery? I might have it checked at the battery retailer using their starting/charging testing machine.

Alternator over charge the battery ,i have a tune up done on the van but no fire i put it on the machine result igin coil change it no better

If the alterantor is OVER-charging the battery (or not charging it, either way) then the regulator is most likely bad. These are not generally replaceable, so you have to replace the whole alternator.

i hope this helps,

Put a new battery in. alternator not charging-put in a new alternator still not charging. machine showed a drain on the battery what could this be?

what machine? who tested it? who sold you these parts you didnt need? take it to a qualified repair shop that knows HONDA and can fix it for you, instead of taking monbey from you for uneeded parts.

325ci wouldn't turn on so I got a jump and then when I turn it of

A working alternator can try to charge a bad battery but won't. Have the battery and charging system checked with a machine. Also note: your alternator is not designed to charge a battery. It is made to maintain the state of charge present in the battery. If the battery has been drained, then jumped, the alternator can put a surface charge there but will never fully charge the battery...This is only done with an external battery charger. Not doing this will over-work the alternator and shorten battery life!
