I installed a True dual battery isolation kit UTV-SBI-18. When I use my winch or my Accessories and they are connected to the auxiliary battery and fuse block the voltage drops on the main and the auxiliary Battery ,is this normal?

Yes. Its actually drawing from both until the voltage remains under 12.7+- for 10 seconds or so.
I was wondering the same thing. So when i turn on my light bar and engine running both read 14.40, but when i turn on the the light bar the voltage drops by about 3.0 volts for each meter, is this normal..
Also should I be running both neg cables to both batteries ..i have the second battery hook up to ground chassis and stock battery is stock setup except for the + cable going isolator.....
