well lets see ive replaced my alternator 3 times and my battery twice in under 6 mmonthts.... i use to have a system but havent had it on for the last month and my car still did it again today....
i will be driving and my gauge lights will turn off, my gauge will stop working, ac stops blowing, headlights dim, and radio turns off, when at a stop the idle gets low and will some times die

i have a obd1 jdm h22 in my obd2 ek i have a chipped p28 im running a obd1 to obd2 conversion

anyone have an idea or know what it could be

 

Probably a bad ground somwhere. Or probably a bad connection on the Alternator somewhere.

 

your spelling? maybe a short circuit from when you removed your "system"
