So, about a month ago I installed the UR Underdrive pulley. One thing that I noticed is that my battery voltage drops whenever I am stuck in stop and go traffic for a while and sometimes it drops so low that the Z shuts down. Today it sorta freaked me out because it the voltage dropped when I was getting off the freeway. The car died as I entered the off ramp and I almost went into a wall without my power steering.

Is there anything that I can do to keep the voltage from dropping and shutting down the car? Would a different battery help? Should I tighten the belts more? Would a grounding kit do anything?

Help me out fellas

 

its not the pulley. Its probably your alternator or battery.


I had the UR pulley, it only underdrives by 15%. You may see a volt or two less on the gauge, but that can be attributed to heat as well. I never had voltage issues, even with the low idle.

 

Are you still running the original battery? Might be time to swap that out for a new gel cell

 

Yeah, I still have the original battery and I am at 45,000 miles. Hopefully that is the problem.

Can you recommend which one I should buy?

 

just wanted to let you guys know, it was a battery problem and it didn't have to do with the Pulley.

Thanks for the help
