CHEVROLET BLAZER BATTERY PROBLEM

2001 Chevrolet Blazer • 132,000 miles

Just had the ABS module and fuel pump/float changed. After driving from repair shop, the abs, brake, security and battery light came on and the fuel gauge and heat gauge went to 0/E. When you tap the brakes they go off but come back on. Any help is appreciated.

Have the charging system tested. When they find the generator is defective, replace the battery too unless it is less than about two years old. These generators have a real high failure rate due to the huge voltage spikes they develop. The battery absorbs and dampens those spikes, but it loses its ability to do that as it ages. If you leave the old battery in there, repeat generator failures can be expected.
