Help Electrical Gremlin! 2001 Blazer
The other day I was driving down the road and all of a sudden my lights started dimming in an out, after a minute or so my gadges started going crazy and the engine started cutting in an out, it ultimatly broke down and I lost all power.
The power tested good for a few minutes after getting a jump, a steady 14v was read on the meter. However it died shortly after rolling down the offramp of the freeway. I decided to replace both the altenator and the battery for the sake of it.
After replacing the altenator I drove it around a parking lot for a couple of minutes and it seemed fine, however the problem came back once I hit about 25mph. I managed to limp it to a friends house that was near by.
Keeping it at slightly over 1k rp's and cruizing about 25mph it seems to stay stable most of the time. Going over that limit it's hit or miss, the gadges start going nuts and the battery starts reading around 9 volts, everything goes dim and the engine starts cutting out again.
