Hi:

I experienced what seem to be a low battery problem and charged the battery. Worked great but I noticed that the charger continued charging. Decided to disconnect ground cable to see if there was some fault. Continued charging. Subsequently connected battery and found that the ignition didn't seem to permit engaging the starter. Also, a dashboard idiot light (red LED) flashed three times as did the marker lights. Two or three series of these and then nothing. Attempted various permutations of leaving the key in the on position while connecting the ground cable etc. No joy.

Is there a secret squirrel switch somewhere that needs depressed or is this now a 'shop-job'?

Sounds like you have an aftermarket alarm installed and it is causing this issue. Have it removed.
