Burning Out 6V Head Lights....

[LODI3QTR]

My '50 Suburban burned out a Head Light the other day, No problem I replaced it. Drove into the city during the day, When I went home at night the new Head Light burned out right away. Then I noticed my Amp Gauge had went up to +40 then back to 0 then back to +40. Drove home and lost Two dash Gauge Lights. Next day replaced another Head Light, Same thing Happened. I'm thinking the Voltage Regulator is the Problem. I've been driving the for 2 1/2 years with no lighting problem till now. Does any one have any other ideas. Thanks in advance, Mike "LODI3QTR"

I am thinking you need to check your output with a voltmeter and quit guessing and come to terms with the problem..

of course you will have to check it while it is acting up, could be only when driving.

Is good to have a helper with this, while you drive ....

do it without the headlights and hook up your meter and have it beside you on the seat....it is not difficult...in the man time..check your regulator ground...

uggg, forgot about the battery under the floor boards ...  was thinking the helper would ride on the fender while lodi drove around the block

Two likely culprits: Faulty regulator or mis-wired generator, assuming you have a generator system and not converted to alternator.

Thanks for the input Checked it with the Voltmeter. It was putting out 11.8 Volts at times then dropped to 7v then back up to 11.8v again. Ordered a new Regulator.... Car is all Original.
