Hi,
'88 XJ Reman 4.0L and AW4 Tranny, A/C, Open Cooling System with CSF Rad, Tranny and Oil Coolers. Megawatt A/V/GPS/Computer/Lights/LEDs/etc. 170 Amp Aftermarket Alternator.
Ok, Just changed my Red Top with a Yellow Top Optima (damn, was $206.38 at Pep Boys). I turn on all electronics, everything's fine the Dashboard Voltage Meter at around the 11 O'Clock position (little before 14V).
BUT, as soon as I turn on the A/C the AUX FAN kicks in and the VOLTAGE GUAGE then drops to the FIRST line or notch. That FAN draws alot of current.
Plus, my LCD SCREEN nearly goes blank due to lack of current. It returns to normal soon as the A/C is switched off.
btw - I only have an oem 94 AUX ELECTRIC FAN now that's coupled with the oem CLUTCH FAN. I removed the second ELECTRIC FAN and put back the CLUTCH FAN.
Should the needle on the Gauge drop that low or is it normal? Where does your VOLTAGE GUAGE read after switching on the A/C? The above is when the engine is idling.
Thoughts, suggestions?
Thx.
