Alternator is a B&C 200G. Battery is a small Odyssey.
Alternator is Permanent magnet, so no field windings.
During testing the 1st regulator, we measured DC&AC voltage between regulator casing and the engine. This was 0V, indicating earth is ok. Resistance was also 0 ohm.
Regulator is mounted on a block of wood (casing not earthed) on the engine side of the firewall. I don't believe it gets hot, but may need to check.
There is a 10,000uF electrolytic smoothing cap on the DC side of the regulator. The troubleshooting notes on the B&C website suggest that this is critical to correct operation. Next steps will be as follows;
1. Triple check the wiring
2. Test the smoothing capacitor
3. Test the voltage/waveform on the AC side
4. Try a different battery
5. Check the temp of the regulator during operation
Anyone any other ideas?
cheers,
Al
