As of yesterday, I completed the 1G to 3G conversion on the truck in my signature for around $40.00. U pull it alternator (tested and passed at Auto Zone) and harness, napa mega fuse holder, 175 mega amp fuse, ring connectors and wire lum.
I have read several post on the conversion, but have not been able to find where anyone posted the results of their conversion, in relationship to voltage output.
My results are as following:
At approxmately 60* this morning; battery voltage was 12.32.....
High Idle was 14.15 volts at 950 rpm with no load....
While still at High Idle, I added A/C and High Fan, radio and doors open, to create load-- voltage stayed at 14.15 volts
While still at High Idle, with A/C, High Fan, radio, doors open; I added Hi-Beam headlights to the list; with a voltage output of 14.06
Final test of all the above plus windshield wipers on high voltage was 13.91.
Returning to idle speed of 550 rpm and the load reduced to just doors open and radio on voltage returned to 14.15
Further testing at regular idle of 550 rpm
Later in this morning, with a warm engine and 73* outside; I performed the following test.
Before cranking with a voltage of 12.41
At idle with no load applied voltage was 14.11
With the same rpm with Doors open, A/C and Fan set at High and Radio voltage dropped to 13.92
Adding Hi-Beam headlights voltage dropped to 13.00
With the last addition of the Wipers on High the voltage drop went to 12.57
Unloading the circuit the voltage returned to 14.03 after two minutes of idle......
My question is this, does this alternator fall in the line with those of you that have the 3G alternator conversion or have I messed something up with this install?????
