If the OP has good terminals and cables pass a visual, he's had it "load tested" so I'd say he's likely fine.

Yours is a '94 isn't it?

Yes I own a 94. The battery tested low under load. It had a slugish start up. The battery was over 7 years old. And with a new battery the light does not come on. And all the connections look fine.

I guess I need to take a closer look at my 94.

Glad to read you got it repaired.

I also hope that who ever installed the battery also did a visual inspection of the battery cable end...making sure that they were CLEAN and not corroded....and that they are TIGHT!!!

FOR WHAT IT IS WORTH:

Having the information on how to access and pull up data so IF you get a 'SYS' light flashing again...you will not be in shock on what to do. Doing this does not hurt anything IF you follow the instructions....and ANYONE can do this if they can read, comprehends and follow instructions. Because I KNOW I can not be the only one who can do this.

Glad you got it fixed. My SYS light was bad battery terminal bolt. Replaced both with Dorman help parts and haven't seen the light in a year or more.

My 2003 3500 pickup would tell you the battery was going bad by not turning on the dash. Drive 5 miles shut it off and restart and the dash came to life. Dealer told me he could program the dash voltage test out but I left it alone. Trying to convince the girl t the parts store I needed two batteries was a whole different adventure.
