P1000 Voltage with dual isolated batteries

[Medic828]

I installed the dual battery using the tru isolator kit. When first starting the unit the main battery voltage will bump up to 14.3v as it should, the acc. battery voltage will then jump to 14.3v as it should. My question is, when I turn on all led lights I installed, the voltages for both batteries will drop and read 13.7, is this normal or should only the secondary voltage drop?

Normal

Thanks, I couldn't see how it would be abnormal, but wanted to confirm for peace of mind.
