75 volt signal loss

I have a 2014 gem EL. Just installed lithium batteries in it. I’m not getting any power to the key switch. When I flip the power switch my voltage drops from 75 to 5 volts. Any advice would be appreciated. Thanks

Test voltage at battery. Some batteries are not suited for ev use.

How are you measuring this?
(where exactly are you placing your meter probes?).

What batteries did you install? Retrace your install steps. Verify that you did it correctly.

Hey Gemac
Where did you go?
8 days is past the limit of my attention spa…
Oooo.. look over at the shiny other thing…
