Recently bought an IH 656 Hydro Diesel. Shortly thereafter broke my leg falling off my roof and have been laid up for a while. Starting to get around a little and can use the 656 since its hydro and I don’t really need my left leg.
Problem I’m having is it seems to be getting harder to start. I know its indirect injection so suspected the glowplugs first. Here’s what I've don thus far.
Checked all the plugs one at a time with an ohmmeter and all were about 1.7 ohms.
Added a used IH Glowplug Meter from an 806 and replaced all the wiring with 8 gauge THHN from the starter solenoid (where the battery cables attach) through the switch & meter to the junction block at the glowplugs. Replaced the wires between the glowplugs with 10 gauge THHN.
After this when pushing the glowplug button, the newly installed gauge barely makes it to the middle of the 3 dots. Thought that funny so checked each plug individually through same gauge. Got no movement whatsoever in the needle unless at least 3 plugs were hooked up. Again seemed strange
Checked each plug individually through another generic ammeter and each plug draws approximately 8 amps. Remove 2 of the plugs & verified that the plugs did indeed glow red.
I assume now that the used gauge I installed either is the wrong one or isn’t working correctly.
Tractor still is very hard to start at 60 degrees even with a couple full minutes of glowplugs first. Once started tractor seems to run fine. Takes a couple minutes for the smoke to clear up and then runs great!
What’s my next step?
