Hi, If the glow plug is closed when cold, but opens when it heats up, then you need to watch the current. Otherwise, the current draw will be relative to the resistance. Not that it really any more difficult to stick your meter probes on the feed wire and the plug tip than it is to stick them betwee...

Hi, Glow plugs are resistors, so checking them is easy with an ohmmeter. Just pull the power lead off and measure the resistance between the power terminal and ground. Now, what it ought to read, I don't know as that varies by plug make and type. Dozens of ohms to a couple hundred, I would expect. H...

Hi, We had 2-3 inches on Tuesday, followed by 4-5 on Wednesday. It was hard to tell as it was melting from underneath all the while. It was freezing rain on Thursday, but I used a backblade on my 5103 (has a canopy, the M doesn't) and plowed slush. Heck, it was more liquid water than snow! Yesterday...

Hi, Last night, I got to poking around some old car chat boards, and there was some chatter about issues with new points in old cars. It seems a lot of newly made points are using sliver plated copper for the contacts and those need dressing a lot more frequently. Perhaps this is what has been happe...

Hi, Ok. No 6v system had a resistor between battery and coil. None. Ever. The coil.*is* 6v. Early 12v systems had a 6v coil. So to not fry the coil, they used a resistor between the battery and the coil. To ensure that 6v went to the 6v coil when the 12v battery was under starter load, they had a by...

Hi, The contact points were made with a Silver contact on the Negative side, and a Copper/Silver alloy on the positive side. This reduces electromigration between the contacts. If the polarity is reversed, then electromigration is accelerated. It has to do with electron flow between metals higher an...

Hi, Those bolts keeping the tilt adjust wedges in are not supposed to be there. They should have much shorter roll pins. If you remove those long bolts sticking out, there should be clearance enough for the main pins on the angle adjustment arms to slip through the blade frame. The roll pins just ke...

Hi, The resistor on the VR sets the point for the voltage relay to open and close the field coil feed to the generator. As that relay opens and closes, it kicks the generator output up and down to hold the battery at full charge voltage (which is in the region of 7.5 volts). If a machine has been co...
