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. ---
