Threw P2503 code, it a low voltage output code... nothing else threw. i am still reading normal on the dash guage at right about 14 or a bit above. should i just disconnect the battery and let the comp. reset and see what happens. is this code a big problem or just a minor mess up? BTW i was runnin a power joke at the time and might have thrown it then but i did jump start a my railroad company boom truck on monday, could that have thrown it?
