From memory the injectors are not in the way. If the injector lines are they can be removed easily.
You can check the controller by switching your multi-meter to voltage; energize the controller and check for voltage at the glow-plug
I'd get out your voltmeter and monitor the voltage applied to them if any during the preheat cycle. No voltage, not workie. Somewhere is a temp controller that probably has an ambient temperature monitor, or monitors something in the engine that is affected by the ambient temperature that allows voltage to the plugs. Colder the temp the longer the voltage is applied. Just because the dash light is on doesn't mean they are getting voltage. A service manual should have a wiring diagram and some have pictures where different things are located within the tractor.Hey gang, I'm a proud new owner of a 1992 B7100 HST-D. I read a bunch of your threads before buying and then took delivery. Everything worked great for the first 2 weeks then I went out the other day and turned key to on, Glow Plug indicator light came on but the Controller coil wouldn't glow and thus she won't start. Am trying to figure out if it's a bad glow plug or a faulty controller. I've tested each plug with my Ohm meter and they are only reading .4 ohms which seems to be well within range. Battery is fully charged.
Does anyone have a fool proof way of testing Glow Plugs or the controller for that matter? I'd hate to buy 3 plugs, replace them all and find it's the controller. Neither part is returnable and my local dealer doesn't have the glow plugs in stock. They do have the $22 controller. Thanks for any help you can provide this first time diesel owner. Can't wait to get better aquainted with my new toy!
They might find out even sooner this way, if they're standing in a puddle.Well most glow plugs get their circuit completed thru the engine block, so holding one in your hand with the hot wire connected would not be very eventfullas no current could flow thru it to heat it up
