Josh, What's the advantage of adding an auxiliary solenoid to the starting circuit?

Its pretty generic, maybe it will help. https://youtu.be/Mp2cGDa1VOU Josh Muckley S/V Sea Hawk 1989 C&C 37+ Solomons, MD On Jun 5, 2016 11:13 PM, "Dr. Mark Bodnar via CnC-List" < cnc-list@cnc-list.com > wrote: Stopped by the boat today planning to get prep'd for some work that need to get done. Figured I should kick the engine over just to make sure everything was running smoothly. Unfortunately I got nothing (absolutely nothing) from turning the key. Batteries seem fine. Able to run radio - and no visible dip in power to the radio when trying to turn over the engine. I had a similar experience a year ago after running the diesel for a few hours - wind came up and we sailed for a bit, but then couldn't re-start. That day I easily found a loose wire (clearly it had shaken loose with the engine running for a long period) off a clip on the starter solenoid (?). That was my first check today - but it was attached. Pulled it off to clean contact but no effect. I figure there are 3 possibilities 1- ignition key failure - no signal to the starter to kick over 2- starter/solenoid failure - I doubt this as I'd expect some type of noise or power dip indicating that something was seized 3- electrical connection failure - I can see a large wire leading to what I presume is the solenoid, plus a couple of smaller wires connected as well. Nothing obviously disconnected I need to head back down to the boat with a voltage meter - try to figure out what is going on and hopefully find an easy fix! Any advice is appreciated. I presume is the key is working them I'd get a voltage spike at the solenoid when the key is turned. If nothing then it suggests either 1 or 3. Where should I see that? I expect I'll pull the panel and check the contacts behind the ignition key - maybe try hot-wiring it if I can figure out which wires are needed Should I use automotive jumper cables to bypass the starter and try to spin the starter/solenoid directly? The engine is a Volvo 2002 18HP Thanks in advance for the advice, Mark There is no cure for birth and death save to enjoy the interval. - George Santayana _______________________________________________ This list is supported by the generous donations of our members.
