Does the relay get wired differently than the existing one is the new glow plugs any different than the old ones are there one to one replacement and I guess you have to use this relay for the new glow plugsI used the gear reduction starter with a 350CCA garden tractor battery. The glow plugs are the modern NGK 12v replacements using a Motorcraft glow plug relay from a 1983 Ford F250 6.9 diesel truck to power them. I drove it to the local gas station yesterday to fill the tank, which is about a quarter mile away. Anyway, it hadn't been started in about a month. I operated the glow plugs for 20 seconds since the ambient temp in my garage at that time was 55 degrees. It started immediately.
Now a friend of mine uses a Deka battery rated at over 400CCA in his 782D with the original starter.
In stock form, there is no glow plug relay. All of the glow plug circuit current is run through the switch, and the dash glow plug indicator is a built in resistor for the circuit to get the voltage down to 9V to run the OE glow plugs. The new updated NGK glow plugs are made to run off full battery voltage, and the relay allows more current to run them versus running the current through the key switch. This extends the key switch life dramatically, since the internal contacts don't arc nearly as much. Side benefit is quicker starting since these glow plugs are hotter and get hotter quicker.Does the relay get wired differently than the existing one is the new glow plugs any different than the old ones are there one to one replacement and I guess you have to use this relay for the new glow plugs
Did you wire the new relay through the key switch or did you install a separate spring loaded switch for itThat relay should do what you need. That is the glow plug relay for A 7.3 IDI Ford/IH Diesel. That powers 8 glow plugs for ~10-15 seconds… the 3 for your 782D should be a cake walk.
(One of my other hobbies is Ford Diesels, so I recognize that by sight… lol)
My oil lite is out us to come on when I started the engine now it stays out how. Do I troubleshoot itInitially, I pulled out the insert easily with a pick. It was an interference fit, albeit a bit loose. Upon installation, I staked the aluminum cover with a punch to prevent the check ball and insert from popping out. Theory is that at some point when the filter was being replaced, the spring pressure popped the insert out, and the ball was lost. When a previous owner put the spring back in and the insert, they might have not known about the check ball. Then when the engine was started, the oil light was illuminated. When they couldn't figure it out, they disconnected the oil switch, and the light was out.. Obviously not a good way to "fix" the issue. The mere fact that this engine survived this long is a testament to the Kubota design. I really don't think any damage was done to it. There was no glitter in the oil, and no weird noises to suggest bearing damage. A oil pressure reading will prove this. Next project is the glow plug system upgrade.
It is wired through the original key switch. You must bypass the original dash resistor indicator, which is super easy to do. Simply remove one of the wires, and install that wire on the other lug and tighten the nut. The existing orange wire under the hood connected to the forward glow plug is removed from the glow plug and placed on the new glow plug relay.Did you wire the new relay through the key switch or did you install a separate spring loaded switch for it
Typically, the bulb fails. If the bulb checks out, then you can take the lead at the oil pressure switch on the block, and ground the lead. The bulb should be illuminated at that point. If it does not the wiring or connections are bad. If the bulb does light during the testing, and not when the key on engine off, the oil pressure switch is bad. Kubota still sells them.My oil lite is out us to come on when I started the engine now it stays out how. Do I troubleshoot it
