Raymarine chart/gps help

[SEA DREAMS]

2 year old raymarine A65/DSM25 had started started beeping and reads warning..battery 10.2volts and turns off. Batteries are new and the connections are tight and clean. Any help? Thanks, Mike

get annother voltmeter & check your battery voltage, & chargeing voltage, if both meters agree, your batteries are weak, --possible chargeing problem or other drain on batteries, or a bad battery, bad wiring, etc.

you mentioned "connections are tight" did you check ALL the connections, not just the battery terminals?

if batteries check out ok, start checking wiring to unit,
