The wife's '85 123 would not start Saturday. I jump started it and drove it to where I bought a new battery about 18 months ago.
The battery showed a low charge but tested O.K. and the alternator,(new)checked out fine. We shrugged our shoulders and I drove off.
Today, It would not start again, what could be the problem? Help please!
