Canadian Hummer Club Forums

Hi everyone

I am a new member here, I recently picked up a 1995 Hummer with a supercharged 350 gas engine. So far I am really enjoying the vehicle and last weekend I went for what was meant to be a basic trail ride. I got completely buried in the snow, but knew my winch would get me out. That is when I found out the winch doesn't work very well. Here is what happened, I pulled the winch cable out and to a tree and started pulling it in, once the weight of the truck was on the winch it really does down and eventually couldn't move the truck unless I left it for about 20 minutes at which time I could get about 2 more inches ahead. I noticed my voltage would drop down to 8 when the winch was on and figure the battery or alternator is the issue. The battery is a new interstate 800 CCA battery and as it is gas I only have one battery. Could you help point me in the right direction. I was thinking of replacing the battery with a sears die hard platinum deep cell but don't want to was waste 250.00 if this would be caused by something else.


Thanks

May need to have a dual battery hookup and a heavier alt. Winch may have issues as well. What make of winch? how heavy?You need at least a 10000 # winch for a H1, and sometime you need to block the cable to get more pulling power.

The winch is a mega winch 12000 lbs winch. It looks like this company doesn't exist anymore, but it has a low speed and high speed setting and both draw my appease down to 8 or 9 even without any load on it. Does the Hummer alternator have the power required to run a winch like this. If not is there an aftermarket brand that could do it.

How do I test to see if it is the winch thats an issue over the alternator. I have an amp and 6 auxiliary lights and the truck doesn't drop down in a per age with all of that on at the same time.
