Is there any way to adjust the output of Van's (60Amp) alternator? During flight my battery is reading 16.5 V and 14.8-15 V at rest.
I do not have any overvoltage protection and am worried that this might "cook" the battery. Has anyone experienced this problem and what remedies.

Might want to look at your voltage gage--at rest battery should be about 12.6 (I don't know how you could get a battery to read higher than this) and charging voltage about 13.8-14 volts--use another voltage meter to check. Your alternator may be fine.

Depending on what voltage regulator you have, it may be adjustable....

Thanks to those who responded to my Voltage question. Turns out it was a gauge problem - don't know how it went out but have managed to re-adjust gauge. Reads 12.8V fully charged at the battery
