hey had a problem this weekend.
I suspect it is the battery. let me know what you think.
havent done any tests but i know i have a weak battery

I was driving this weekend and everything turned off in the interior(radio, lights, and even the speedo/tac) but the motor still ran. parked it and next day it barley turned over and couldnt get good cranking rpms. I have jump this battery alot in the past and am wondering if anyone has seen this same issue.

car is 98 civic ex with jdm gsr with bolt ons. stock jdm ecu(p72)

 

I would test the alternator and battery at like autozone. or Oreaily

 

the battery should get charged by the alternator while the motor is running check the alternator and replace your battery you can get a refurbished battery for 20 dollars if you trade in your old one
