I'm using the PWM adapter to power the 2 IBEC's powering the ignitions for my P-38. both IBEC's for the left engine are plugged into one port of the adapter using a multi servo connector block. I've had 2 PWM modules fail and cause the engine to flame out one in flight. the port seem to work when first turned on until I start the engine and after a few seconds the voltage from the port (3) the IBEC's are connected to drops to around 2 volts, I programmed port 4 to the correct channel and moved the IBEC's to that port and It worked fine for one flight now that port has failed in the same manner. the PWM adater is rated to 20 AMP's but how much can each port handle, both ignitions at full throttle should be pulling no more that 2-3 amps combined. Should I just use the signal from the PWM adapter to control the IBEC's and feed them power from a separate source or run them from 2 separate ports on the PWM adapter. Looking to see if there is something that I'm missing before throwing in another PWM module, the one on my right engine is setup the same and has not had a problem so far.
