Hummers: k5 blazer, us army mil, jumper wire


Question
I have a k5 blazer cucv the thing won't charge the batterys bats r new and had the alts checked out there fine thing jus won't charge don't know what to do

Answer
VOLTMETER INOPERATIVE OR IN YELLOW (UNDERCHARGE) ZONE; GENERATOR LIGHTS
OPERATING PROPERLY (ALL EXCEPT M1010)
Step 1. Check alternator belts for looseness or damage. (See paragraph 4-2)
Step 2. Check 20 amp ignition fuse and 10 amp/28 v (voltmeter) fuse. (See
paragraph 4-1 2)
Replace fuse if burned out.
Step 3. Remove voltmeter relay. (See paragraph 4-9) Start engine. Using jumper wire,
connect white lead terminal and black lead terminal.
If voltmeter reads in green zone, replace relay.
If voltmeter does not read in green zone, trace circuit from bus bar ground to
fuse block.  

Chad,

Voltmeter relay is located under the dash near the steering column. I also recommend tracing all the wires in the charging circuit and performing continuity checks because the wire harness has fusible links.
