My grand Rapids unit shows 12.5 volts. Goes down to 12.3 with radio and transponder on. landing light or strobes take it below 12.0. Installed new regulator( Kawasaki) and new battery. Still persist. Any Ideas ??

Dennis, have you checked a direct voltage at the battery 

to compare? My newly fitted MGL EMS showed only about 

11volts, but the battery voltage was 12.9 and there was an 

adjustment in the set up program that allowed me to make 

the two read identically.

Also please give additional information :



- Was your electrical system performing well before ?

- Or is it a new or modified installation, etc. ?

- Is a description of schematics of your power circuit available ?

- Have you checked that your actual installation is in accordance with 

the intended schematics ?

- Did you check every connection ?

- Etc..



Best regards,
