Im losing voltage - I need help

[turbodsm18]

Alright so I put in a walboro 255Hp fuel pump and rewired it to the battery. When I put on my blinker you can hear the fuel pump losing voltage when the blinker flashes.

Also, when I start my car, one of my belts squeaks real bad for about 10 seconds, could this be my alternator belt is to loose and isnt fully charging the system. Oh and my alternator only has about 20,000 miles on it.

Thanks

Tighten that belt. It'll help the squeaking if nothing else.

When your car is running, put a voltmeter across the battery terminals - if it reads between 13~14 volts then your alternator is working fine. You really need to tighten that belt - as hard as you possibly can. If the belt is slightly slack it will adversly determine the output voltage of that alternator. The belt squeal on startup is a dead give away that the belt isnt tight enough.

Did you correctly wire that new fuel pump? You didn't wire it on constantly to the battery right?

Tighten the belt, but not as hard as you can. If its to hard it can wear fast and damage the bearings inside the altenator. The best advice about the belt is use common since when tightening.

Like stated before put a voltemeter on and see what happens.
If you have a turbo timer, most have a built in voltemeter you can read.

Thanks everybody so far, I will definately tighten that belt. Also my fuel pump is wired throught the Vfaq.com way.

Anybody else have any other advice?
