[QUOTE="timetraveller, post: 11921, member: 456"] That is good advice from Howard except that I would disconnect the positive side of the battery, assuming that you have negative earth, and then with everything switched off see if there is 12 volts passing between the battery terminal and the positive lead. If there is then something is connected when you think that it is disconnected. I suspect that Howard's idea of the ignition current not going through the ammeter might be correct. When running the engine at enough revs to get a decent charge the voltage across the fully charged battery terminals should be 14.3 volts. If it is lower than that then either the battery or the charging system is u/s. A decent 12 volt battery will be at 12.9 volts after standing overnight having been run and fully charged the day before. If you have just come in from a run then the battery volts should be at 13+ volts. If all else fails and you do not mind a non original look then why not fit one of our car alternator kits. They fit really well into the space on Comets where the rear cylinder would be on twins and they give a reliable 30 amps! :cool: [/QUOTE]
