Alternator Installation Instructions
Alternator Installation Instructions.
Many of our kits are designed to be "upgrades" or "conversions", and they will come with very detailed instruction and conversion parts. This document is for a simple situation where you are replacing an alternator with the same type, family, model, that is not a conversion or upgrade. We assume that you have or had a functioning alternator and charging system prior to this change. If there are problems in the wiring or vehicle a new alternator will not solve them. You need to have good cables, connections, battery and grounds for the system to work properly.
Disconnect negative battery cable from the vehicle battery.
Disconnect the B+ Cable, regulator plug, stator plug from the old alternator.
Remove the old alternator from the vehicle.
Install new alternator re-using the mounting hardware, making sure all fasteners are tight and the pulley is in line with the other pulleys and the belt. Make sure when installing the new alternator that the mounting feet and brackets are clean metal to metal connections, as the alternator relies on these surfaces for a ground (-)
Reconnect the plugs check for any damage or corrosion and replace them as needed.
Connect the positive power B+ wire to the B+ post on the rear of the alternator. Tighten the nut securely but not overtightened as it could break. This post should look very similar to the one you removed and the wire is reconnected. Make sure the wire is in good operating condition. If you have dual batteries, it is a known issue for the crossover cable to be a problem, this will cause the main battery to over-charge and the extra battery to under-charge, sometimes the wire will get hot or fail. This condition is not caused by the alternator and is not eligible for warranty.
Connect the negative battery cable to the battery.
Start the engine and make sure the alternator is charging. OEM voltage should range 12.6 - 14.8 volts as measured at the B+ post on the alternator and the battery.
