2014 Phaeton 42' LH voltage drop
We have a 2014 Tiffin 42"LH Phaeton. When plugged into shore power you turn the key on and the lights dim a little and I lose 3 volts AC at the outlets. I am told that when you turn on the key the i...

Here is what I gleem today. First I was wrong I did not turn off the inverter in the bay, I thought I did but really did not. It seems that the ON / OFF switch is a momentary switch which takes a light finger... I did not get a steady green light like the manual said if it is on. I did get a green light flash every 8 Sec showing that the inverter was in standby mode, and there was float changing. It almost takes 2 people to check these things. One on the remote taking notes and one in the bay.
Inverter in standby mode shore power connected.
Key Off 13.5 volts 4 amps at inverter remote panel
Key On 13.0 volts 120 amps decreasing to 90, 40, 20, 0, 40, stable 18 amps (15 sec for this to happen)
Key Off 13.4 volts 4 amps
Key turned on (AC side digital meter used) Power dropped 2 volts 122 to 120 overhead light dimmed just little Voltage differents between different outlets only a couple of volts All within specs.
Key turned off all outlets jumped back 122 or where they were before.
To me turning the key on should have nothing to do with the overhead lights which are on the DC side. The inverter should be in standby since shore power is passing thu to handle the load. With shore power connected the inverter becomes a battery charger. When the AC goes away, the unit becomes an inverter. Still does not account for what is happening.
