Painless High-Output Alternator Wiring Kit with Boot for 1965-1995 Mustangs.

This add-on kit is for Mustangs with alternators that produce more than 65 amps. Provides you with heavier gauge wiring and connectors to complete the high-output alternator installation process quickly, easily and safely.

Vehicle Fitment

Rated 4 out of 5 by from Gen Wiring Updated my generator to the Powermaster gen/alternator unit so that when viewed, appearance was of a generator. Original wiring was more than suitable and better quality than the Painless wire cable. Not required if you have original factory cable.

What will be the max amp this cable can handle. How many gauge is this wire?

Asked by: Ronnn
Most of the Painless kits I’ve used in the past included power cables that were properly sized for the anticipated load. I’m a little surprised by the stated specifications of 10 gauge for the 6’ length and 8 gauge for the 3’ length. The longer 6’ cable is a smaller gauge than the 3’ cable and depending on how much current is going to be expected from these mismatched capacity cables, the reduced efficiency could become a problem.  When working with automotive D.C. power systems such as battery cables and high output charging systems, the accepted standard is for the positive and negative cables to both be the same AWG size regardless of the length. A common mistake is when a gigawatt stereo installer thinks the positive cable has to be massive to handle the extra load but the negative cable size is less significant. Then when he twists the last two wires together and fires it up with intentions of impressing friends in the next county , he gets instant signal clipping and distortion. His killer amplifiers with LED’s that blink to the music are starved for power because his mismatched power cables have excessive voltage drop.  The typical charging system upgrades on most modern cars is usually double the stock amperage rating. I can’t imagine anyone going to the trouble of bolting on a new generator/alternator for only 65 amps. When I decided my GTP needed more bass from the little Bose factory audio system, the first step was a power system compatible with the demands of the new amplifiers and two JL Audio 10W6-V3/ D4 subs. The OEM alternator was rated at 110 amps. The new Mechman amp tested at 240 amps output. Along with a new deep discharge battery with 1000 cca, it was almost complete. It needed all new cables. Since real copper is very expensive, GM took the cheapest solution and wired my battery and charging system with tiny 8 gauge cables. Just barely adequate for the OEM system. Mechman provided a complete cable set for charging, starting and normal operation that includes MASSIVE 1/0 gauge pure copper cables. Voltage loss is no longer a problem. If there’s a point to all of this madness it would be there’s no such thing as power cables that are too big. Most electrical system problems and caused by small cables without enough capacity. And that’s all I have to say about that.
