intermittent issue... then while driving all of a sudden it bucks once, engine light comes on... then anytime it gets near 3000 rpm it starts bucking like crazy until I back off and feather my way up.

don't know if it is related- but (while my battery IS old) the charging light would come on intermittently.

other day it came on and stayed on, eventually went into limp mode on highway and managed to get home.

Charged battery overnight and drove to work- light still came on.

Went to Autozone after work to check batt/charging. Machine said "voltage too low to test" so I got a new battery since the old one was 7 yrs old :-)

Light still came on but started and drove fine... went to AZ to have them check it and read the code. Voltage was again too low...but code reader said "Battery not connected to module"....

ANYONE? ANY ideas? with EITHER issue?

cannot afford to replace alternator just on a guess... if I'm spending that much... I need to know THAT is the problem...


I'm thinking it is NOT the alt because I doubt I would be able to drive nearly 75 miles JUST on battery power (half of them with headlights on)

Fusible link, perhaps?
