ridergoatee Posted November 28, 2006 Share Posted November 28, 2006 Has anyone had the heater draw excessive juice? watch my guage needle drop close to red when i switch on heater, then there are times also when it doesn't blow heat as it should. Any suggestions? Checked alt, it's puttin out as it should. As soon as you turn heater off, guage returns to normal. Quote Link to comment Share on other sites More sharing options...
Pete M Posted November 28, 2006 Share Posted November 28, 2006 The fan is old, the wiring is old. Current draw goes up as age and corrosion sets in. The one in my 88 used to dim the lights a bit when you turn on the blower. Blower doesn't work any more though, so problem solved. :D Quote Link to comment Share on other sites More sharing options...
Druville Posted November 28, 2006 Share Posted November 28, 2006 mine does the same thing. the heat works so well tho, that i usually only leave it on for a few mins. so i havent really seen a need to fix it. Quote Link to comment Share on other sites More sharing options...
87manche Posted November 28, 2006 Share Posted November 28, 2006 my blower motor drops the voltage gauge by 2 volts the instant you turn it on. Doesn't matter what setting it's on. The factory volt meter is unreliable and inaccurate. Just know what it normally runs at, and it it changes get out your voltmeter and check the voltage in the engine compartment.

Oizarod115 Posted November 29, 2006 Share Posted November 29, 2006 my voltmeter used to never get above 9... but i never had problems... hten one day it decided to go back to normal at 14 and has stayed straight up and down (besides the usual drops with all the stuff on, and when in run mode with engine off it reads 12 (dead on)) my heater doesnt drop the volts at all i don't think... maybe like 1/4 of a volt?
