Glow plug relay problem ?
My truck could not start and the shop found one battery bad and the other one weak. These are DuraGold batteries purchased at Autozone six months ago. They carry 3 years free replacement plus 5 years pro-rate.
Alternator checked out at 85 amps output and was OK.
I took them back to Autozone and once the replacement are installed the truck started without a hiccup.
Some people are telling me that the problem is not with the battery. They claimed it was an issue with glow plug relay malfunctioning and thus battery was overdrawn. I charged the batteries up and it took less than 30 minutes of full charge before the charger meter showed batteries were full and switched into trickle charge mode. However, after five cranks batteries went dead again. I recharged the second time and again it took less than 30 minutes before charger showed they were both full. I'd think that is solid evidence of battery having bad cells.
I am convinced the issue was failed battery. The Autozone fan club claimed nothing wrong with batteries.
So, what is the method to check and verify if the GPR malfunctions?
