Sorry, should have said. Alternator. The car is a TR5.
The story is I was driving home the other night and started to lose electrics. The battery had been fully charged before I left home as I use a CTEK battery charger when the car isnt being used for a while.
First I noticed the headlamps were pretty useless, then the indicators wouldn't flash, then I lost overdrive.
I got home and parked the car in the garage. The following morning the battery was completely flat. I started the car using jump leads. My multi meter indicated the alternator was putting out about 13.5 - 13.8 volts at 2500 RPM.
I bought a new battery and all is OK for now. But the ammeter reading suggests to me that the alternator isn't charging sufficiently.
But I've not long had the car and never had a car with an ammeter before, so I'm looking for confirmation of what I should be seeing.
