Hi, I have started my GT6 MK3 after a long lay up.
Engine runs well even tho the carbs require sorting.
Problem: alternator is not charging the battery.
Engine running, I have disconnected the wires at the alternator and I get 18 volts between the large brown terminal and earth. Reconnected I get 12.46V across the battery terminals.
Other symptoms:
Ammeter shows negative 1 amp
Fuel gauge reads zero (tank is half full)
Ignition light just manages to glow prior to starting then goes out when engine is running.
Engine stopped: Multimeter between the brown termainal and positive terninal on the solenoid shows a connection
Battery is new and recharged, after running the engine for about 20 mins the battery requires a full charge which told me somethings wrong in the first place.
I have purchased a Voltage stabilizer in anticipation.
Any help would be appreciated, thanks for reading this
John
