Battery/electrical questions
I replaced the battery (marginal life left in old battery) in our ‘99 FRC (110,000 miles on car). The starter was clicking and finally started after sitting for a few days. The old battery showed 14.0-14.2v on the DIC while driving. No issues once car was driven. The new battery shows 13.7-13.9v on the DIC. Tech said old battery was suspect for cranking amps. I replaced the battery with the same INTERSTATE battery as always (this has been a habit every other April for the last 10 years). For me it’s a cheap peace of mind - we often take long road trips and don’t want to get stuck in nowhere country. The car is religiously maintained and I have had no other problems🤞Gets 27-28 mpg on these trips.

That 13.7-13.9 volts on the DIC isn’t the true battery voltage that you would see at the battery terminals where you would normally check charging voltage…the DIC voltage is about .3-.4 volts lower so your charging voltage is 14.1 to 14.3 volts which is fine.
