Actually it's quite easy to produce 13.8 VDC from 12 VAC in several different ways, but the best way to test the Tympanium is installed on the bike. If the voltage rises above 14.4 V, it's very likely either improperly grounded or damaged. That value may be lower. I don't know what they're specified to provide.

You actually need a 15-18 volt AC transformer, preferably rated at better than 5 amps, 10 amps would be good. Feed the yellow wires with the AC from the transformer and load the output of the tymp with a 55/60 watt headlight bulb BOTH FILMENTS CONNECTED!(total of 110+ watts), then measure the voltage while it's on load. This will simulate an approximate operating condition.

Have Tympanium gone out of business??? If not why not just pick up the phone and ask them if they would test it for you if you were to send to them along with a stanped addressed return jiffee bag? I suspect they would do so.
