Dead battery - high voltage readout
#1
It appears the battery for the starboard engine on my 31" Tiara Open is dead as I need to push the button between the keys to start the engine. I noticed that when I hit about 3200 RPM the volt meter jumps into red territory. 

Is this the high voltage reading a function of a dead battery or is something else going on?

Can anyone recommend a boat electrician in the Seattle area who might check this out?

Thank you very much!

If the battery were pretty worn down and calling for charge, you might see the voltage running high. Keep in mind on a Tiara, one motor charges the starting batteries and the other motor charges the house.

You know you have a bad battery. Replace it first and see if that resolved the issue before spending any $$ on an electrician.

Agree with Misdirection and would add to check/clean all battery connections. If you have a digital volt meter your battery should show about 12.2-12.4 volts with engine off and charging system off and around 10 volts while cranking. when engine running or on charger you should see around 13.8 volts
