In my O'Day 31, I have 30 year old 2 cylinder Universal Diesel with an intermittent starting problem. Aftrer yard replaced: starter motor/solonoid (with "rebuilt" -no warrantee or paperwork), battery, and glow plug/starter buttons, the yard determined that pressing the glow plug heating button dropped the starting voltage to the starter to 10.8 volts which was insufficient to consistently crank the starter/motor. The yard ran a wire allowing the starter button to be pushed independent of the glow plug button and this seems to have fixed the problem ($1,000 and one tow later). A friend has Nonsuch manual which explains a voltage drop (to around 10 volts) is expected upon pushing the glow plug button. Any thoughts regarding this situation (and whether bypass wire is a long term solution)? Thanks.
