.....Doug has done a very thorough job of investigating the cause of the incident and believes that it was due solely to the substitution of a gellâcell battery for the QAC approved motorcycle battery. Although cautioned by QAC to check the manufacturers recommendations on charging rate and compatiblity with Onan charging system, Doug has confirmed that the battery shorted out and would not take a charge. using the recommended battery, we at QAC have never had an ignition problem in almost 500 hours. QAC also believes that the engine may have been running for some time on the permanent magnet alternator directly supplying the ignition system; only when the throttle was reduced to idle was the output enough to permit the engine to not idle.
.....For additional protection from this type of incident, redundancy could be added by incorporating a motorcycle battery eliminator unit into the circuit. This would allow, at the flip of a switch., for the ignition to run directly off of the alternator. This arrangement would provide a setup similar to a magneto;as long as the engine is turninq over, the iqnition system would function.
