Saw another topic asking about a positive ground, but we're unsure of whether or not that applies to ours, since we have an alternator. That way, you don't have to consider the gauge of the van's wires in the circuit. This connection carries the charging current from the alternator to the battery, and corresponds to the screw terminal on the back of the GM unit. As the title asks, we have a D19 that we took the battery off of long ago, but we can't remember which way the battery goes back on. (Terminal positions shown below. The alternators ground terminal must also be grounded to the boats ground. If he car keeps running, your system is charging. A three-wire alternatoralso has a special switched “turn-on” wire, and this wire can also beused to operate a warning light at the dash. Is this possible? I have heard both sides. (This wire should match charge wire size) Battery must have a clean ground to engine block. If the alternator is wired directly to the other wires it will power everything on its own. how to and why to ground your alternator ghostlyrich. Most use two terminals: some only use one and, best of all, the wires simply plug into terminal sockets on the alternator. Otherwise add a new wire (red) from the - on the ammeter to the Positive Battery Terminal Yellow Green Stripe. • Start engine, increase to high idle (1500 RPM): The volt meter should now indicate that the alternator output voltage has increased to a range from 13. Avoid unnecessary sparks near the battery. Ground runs through many more as previously posted. Had the generator been DC, you could connect them in series to get 48 V but a 48 V battery can be only charged at a voltage slightly above 48 V, say 52 V. Here is another great auto electric tip from National Quick Start Sales on upgrading the wire between the alternator and battery. Running that wire will not cause any issues, actually the main battery fuse in the fuse box directly connects to the wire in the fuse box under the hood, wich then goes straight to the battery so no difference if you add in a fuse. Most ammeters will indicate backwards unless you swap the wires from one post to the other and vice versa. cable between terminal "30" of alternator ignition switch, plug "15" of regulator, or cable between ignition switch and voltage regulator), since alternator voltage would rise and affect life of battery and electrical. Remember, the rear battery is there to help handle the peak loads; the real power supply is the alternator itself. Follow me on this one. These grounds are not optional; they are all mandatory.

Ground either field terminal, and hook the remaining one to a known good battery source, like the start relay stud. Technical Information K20 Swap Grounds Grounds. Also, "battery too dead to for engine to run" is BS too- the alternator can provide *plenty* of energy for a spark. A Volt gauge. Remember, the rear battery is there to help handle the peak loads; the real power supply is the alternator itself. ) or when the IC is with- out power supply (V CE sat of the lamp driver is 2. Winches have their ground return directly to the battery, and with the high current draw of the winch, it far exceeds the current capacity of the alternator, and any recharge rate. It will also limit the voltage loss at the amplifier. You can connect it to the same location or down to the vehicle frame directly, just make sure you sand the metal first. the white wire is only rated for stock alternators, the juice is too much for it, it gets hot and smokes, if the fusible link does not blow it will catch on fire. Helpful Tips. If the battery will charge with the charger hooked directly to the battery posts then you have a bad ground problem. "Battery" runs to the battery side post on your starter solenoid "Gnd" or ground runs from the alternator to a ground on the engin block just behind/below the alternator as well as it feeds a ground to the 3-pin harness. This is why it is best to run the ground directly from the rear of the alternator to the battery. The voltage regulator is internal, and there are no other wires that need to be connected to your electrical system. I would like to wire a battery bank in parallel with my car battery to receive a charge while the engine is on and a solar solution as a backup or alternate charge source in order to power lights/electronics in the field. The two charge controllers that you recommend are really just replacements for the battery isolator that I was going to install, but your alternatives are definitely worth considering. In this mode, the charging voltage at the battery will range from 14. The vehicle Electrical System is a combined 12/24 VDC system. Replied by Wayne613 on topic battery/alternator or fuse/relay problem Before bothering with a diagram or the like, test voltage on the B+ terminal with a DMM if you can get to the back of the alternator (to check before the fusible link that protects the rest of your electrical system from a faulty alternator or any short on that line). Power is supplied to the vehicle by two devices: The battery and the alternator. Bad grounding can also prevent the alternator from properly charging the battery. The purpose of this ground is to take care of the large current drawn by the starter motor. Swap the cables on the battery, wire the alternator like your schema shows, turn on the lights to check the ammeter shows discharge and that should be all.
