Will post S/N later today when back at house...its already on here somewhere from previous posts.
Problem: Yesterday AM got low voltage alarm on bow mount hbird 859. Mid morning the EFI shut down while on plane, thought powerhead let go. First two tries to crank were like it was seized, noticed helm graph lost power. Tried cranking 3rd time , fired right up, idled a bit than ran it just fine. Voltage on dash gauge pushing 13 +, hbird voltage at helm fluctuating, but not getting past 12v. Tested battery voltage once home at 11.8, dual pro charger flashing on cranking bank. Battery is lead acid marine cranking grp 27. Thoughts? Thanks in advance.
