Chrysler Repair: battery cut off: 92 Lebaron, lebaron gtc, chrysler lebaron


Question
I have a 1992 chrysler lebaron gtc and believe I may have an electical trace situation that will have to wait.   On all of my older vehicles including two motor homes the did not have computer system... I purchased a cut-off for the ground battery to prevent a draw and discharge on the batteries.   Since the Chrysler GTC has computers, is it feasible to put a cut-off on the battery ground?    Would the computer system need to be reprogramed?    Thanks

Answer
Hi Breckc,
As far as I know there is no issue with cutting the battery ground circuit or removing the - post clamp. All that it will do is erase any fault codes that are stored in the memory of the computer, but those will reset if the problem is still present when you fire it up again. There will always appear a 12 code after you hook it up, that will go away after 50-100 key cycles.  I would be concerned only if you had an anti-theft system as sometimes removing the battery can cause those to alarm and put the engine controller in a lock-down mode. But if you don't have that, then it is a moot point.
Unfortunately there are alot of fuses that are powered even though the ignition switch is off so there is no single "ignition off draw" fuse that you could pull. Let me know when you are ready to look for the draw problem on the battery as I have the wiring diagrams.
