My 1980 TR7 has had to have a new battery recently as the last one had a couple of duff cells. I'm concerned that the alternator may be putting too much charge in. The voltage gauge shows the output as toward the top end of normal under all circumstances. I checked the voltage at the battery and found it giving 14.5 volts.

Question 1 could the output be too high?

Question 2 What should I change if it is?

I'd appreciate any thoughts. If I've got to splash out on a new unit then so be it.

14.5 Volts at 1000 RPM (and higher RPM) should be OK. The Voltage Gauge normally is as you say towards the top end without any electrical equipment switch on (e.g. Headlights) with the engine running.

 

Basically rev the engine up, without any electrical equipment switched on, and check the voltage at the battery is 14.5 Volts. If yes then no problems.
