This post is about each glow plug being OK while using the boost setting on a big battery charger. I posted last week about my Farmall 706 diesel not starting well at all. I sort of figured the glow plugs weren't working as they should. I found a wire had been hot in the meter and push button switch box. The heat had caused a connection to go bad on the meter, actually causing the plastic housing of the meter to melt. I actually think a corroded connection caused the heat. The tractor sits outside a lot on an auger and has been exposed to its share of rain. I don't think the connection was carrying any current as it just fell apart. Ordered a new meter and will replace some of that wiring. Also, checked each glow plug by disconnecting the wiring harness and using a 12 volt test lamp. Each glow plug carried current. Many, many times in cold weather I have put my Schumacher battery charger with a 200 amp cranking setting on the tractor. Many, many times I have held the glow plug button down for the count of 30 or 45 before cranking and held it there until it clears up after starting. I have read how some recommend holding the glow plug button down for only for a few seconds, then allowing the plugs to cool. Some say a boosting battery charger sends to many volts (14+) to the glow plugs burning them out. What gives??? Why are my glow plugs still working after what would be considered abuse by many?? Thanks.
