If
you are putting your battery in the trunk, Running a Killer Stereo or
using an aftermarket SI alternator putting out more that 100 amps use
at least a number 8 AWG wire between the Alternator and the Battery.
The above drawing shows the proper wiring of the Delco 10 SI Three Wire
Alternator. One of the things that confuses most people is there is
little difference in using this alternator or the One Wire replacement
alternator.
If you are going to use a dash indicator light you might as well just keep this alternator.
If
you are going to upgrade to a one wire because you want a chrome case
then just install the new One Wire alternator and connect it up the
same as your existing Three Wire alternator. If you look at the
schematics below you will see that the One Wire will operate just fine
wired the same as the Three Wire.
If you are installing a Three
Wire alternator in a vehicle that is not properly wired for it you will
either need a dash indicator light or you have to install a 10 ohm 10
watt resistor between the number 1 terminal on the alternator and an
ignition source to properly excite the alternator.
Most Automotive Electrical Problems are GROUNDING Problems. If you're having a problem with something and find there is power to it double-check your grounds (including the battery cables).
