I killed my battery at anchor a few times (thank you Espar!). No problem. As long as you have two people aboard: 1 person lifts the decompression lever, which makes the engine turn over fairly easily. The second person pushes the start switch and once the engine is moving and the flywheel is doing it's job, just drop the decompression lever and she'll start like a charm. Since I normally single-hand, on a previous boat I installed a starter button in the engine compartment specifically for this reason - if the battery was too low to crank against the engine compression, I could open the engine room, lift the decompression lever, then press the handy start button - with luck, the weak battery would then be able to crank the engine, and once it was turning fast, I would drop the decompression lever, and the engine would (hopefully) start. For the same reason, I found (with a voltmeter) where the starter button wires come to the relay that engages the starter. I have been able to start with near-dead battery by crossing th econnection with a screwdriver. A button would be better if I were doing that all the time.

What you're saying is that the wiring though the ignition switch is too small (or corroded, etc.) and is causing a voltage drop. BTW, I played that game hundreds of times with my old VW bug. However, a few years back a friend was working under his car and shorted the solenoid. Since it was in gear, the car lurched and fell off the jackstands, crushing his hip. A big Ooops! |

Yeah,
You sure wouldn't want to do that and have your 14,000 lb yacht fall off the jackstands!! ;-) Jeff wrote: Rodney Myrvaagnes wrote: ...

I suppose it would be a bad idea to attach tie-downs to the propeller!

That's why owner/repair manuals caution to disconnect the battery for ALL repairs - even non-electrical ones. |

Farm tractors are especially dangerous to attempt to start by shorting
at a starter mounted solenoid. There is often a graphic sticker applied near the starter by the manufacturer to remind of the danger. "Jeff" wrote in message ... Rodney Myrvaagnes wrote: ...

What you're saying is that the wiring though the ignition switch is too small (or corroded, etc.) and is causing a voltage drop. No - nothing to do with the ignition switch. If the battery is fairly well discharged, it may not have enough power to crank a diesel against the compression. If you lift the decompression lever (opening the valves, and eliminating compression) the starter may then be able to crank the engine - once the engine is turning, the flywheel will (hopefully) have enough energy to get past a compression stroke, and the engine may start. -- Peter Bennett, VE7CEI peterbb4 (at) interchange.ubc.ca new newsgroup users info : http://vancouver-webpages.com/nnq GPS and NMEA info: http://vancouver-webpages.com/peter Vancouver Power Squadron: http://vancouver.powersquadron.ca |

There is often a graphic sticker applied near the starter by the manufacturer to remind of the danger. The reason is because the farmer could short the solenoid with a wrench and if the tractor was in gear it might well turn over and move the tractor foreward until it stopped on the farmer's foot. In pain, the farmer might well drop the wrench out of reach, and then he could stand out in the bugs and sun until some one came to rescue him. Don't laugh! It happenned to my father in law, and he near died of thirst, heatstroke and then exposure as it cooled down after dark, not to mention embarrassment when the boys got to talking. He was there most of a day and night before he was missed. He was 80 at the time, working as a scarecrow in a large cornfield. He just stopped for a pee, and the tractor moved, probably as a result of dirt settling under the wheels. He says he did nothing, it just rolled a foot and stopped on his foot. The people driving by on the highway just waved back, all day. I guess they didn't know the marine "arms up and down" distress signal. He was within sight of the saint John River. He said later "Never did well water taste so much like rum." Terry K |
