Balmar told me that the regulator may have fried due to voltage spikes which is b.s. as as far as im concerned. I probably put max 2 hours on my new ars-5 before it stopped working.
Just to keep perspective, a voltage spike is a very short duration (<< 1 msec), of an amplitude that can be as much as four to six times the nominal operating voltage. It and the resulting current
spike can and does damage electronic circuits.
A voltage spike can be caused by many events
1. Opening or closing a switch in the circuit.
2. Creating a short circuit.
3. The aforementioned lightening strike, or more insidious, a near strike.
4. Opening of an over current
protection device in a circuit.
That your ARS-5 has only operated for two hours is immaterial regarding damage by a voltage spike, if such a spike occurred. It certainly is not "b.s.".
