I use an alternate battery source (even a LIGHTWEIGHT 12 volt electronic power supply that you plug into shore power works great for this) MAKE SURE POSITIVE IS POSITIVE AND NEGATIVE IS NEGATIVE BEFORE YOU USE THIS!!!
TURN OFF ALL engine battery accessories. You must not overpower the substitute charger.
Get two OLD radiator hoses or heavy towels. Something that when wrapped around the BATTERY TERMINALS will not short out. Connect with clip to the negative and positive battery terminals, loosen and remove NEGATIVE terminal from battery while not shaking the power supply clip off. Wrap in a towel or stuff into a radiator hose. Then do the positive terminal.
You have all the time in the world now. Use it to clean up and repair wiring and terminals and battery holder.
BUT BUT BUT
It is IMPERATIVE that you NOT USE a transformer type electronics power supply for this. If the charger is a black cube and weighs nearly a pound do not use it! These things can surge to 18 volts!
The CORRECT substitute power supply is lightweight, an ounce or two. The difference between the two types of chargers is impressive weight wise.
500 to 800 milliamps capacity is PLENTY! 200 is minimum.
Your computer codes, radio memory will not be lost.
Took longer to write this than it takes to do it all including clamping clips on a solid state electronic gizmo power supply.
