I have a 1989 conbrio been in storage two years.I'm in south Alabama so it is full of antifreeze and the motor is free.I have a fair battery with a commercial charger connected to it on hi amp start position.When I turn the key on dash gauge reads 12 volts but when turn key to start position it drops to under 10 volts and I get nothing.I wonder if the starter could be the issue.I'm mechanical inclined so I need some troubleshooting help.
Thanks in advance,
Tom
