1989 GMC voltmeter/turnsignal problem?

10-18-2007

Hi,
I just picked up a 1989 GMC and I noticed that the voltmeter jumps up and down in time with the turn signals when they are on. All the lights and signals work, but I know that the voltmeter shouldnt jump around. Something is drawing too much current. Any suggestions would be helpful!!!

your alternator may not be putting out enough volts. have it tested
