put a battery charger on it after cleaning the posts and clamps at the cables. let it charge. let it sit with the key in the run position, after 10 minutes or even less, does that light go off ? cycle the key and try starting. let us know if this has any affect.
does the engine crank while attempting?
battery post r cleaned & battery fully charged no change. tried the resetting no result. Theft light stays on . engine will not crank?? All this happen after I replaced the dead battery with a new one??
Tried resetting , how?
Is your connection good at starter for main cable? is there power on the little red/blu wire at the starter relay? during crank attempt? you step on the brake, have it in park? is there power on the start enable wire at the starter s post? while cranking attempt is made?
These had connection trouble at the main cable at the starter. Testing may prove 12v present at rest, but drops 12v during cranking attempt. Without a debris cover. Dirt, oil, debris can get in, added washers should be removed. Increase surface contact and it must be with the nut and post is best results..... The ones with dimmer wheel for lightswitch can accidentally get bumped by the driver leaving light on inside and drain batt.
Yours os 03, the ones I fixed were not that new by like 2 years.
