mikestewart395 Posted February 11, 2014 Share Posted February 11, 2014 (edited) The Interlock button. Silly question I'm sure. I'm tired of not knowing what it is. Edited February 11, 2014 by mikestewart395 Link to comment Share on other sites More sharing options...
ahardb0dy Posted February 11, 2014 Share Posted February 11, 2014 For those times you need to start the truck without stepping on the clutch, like say your on a hill holding the brake and can't take your foot off of it Link to comment Share on other sites More sharing options...
mikestewart395 Posted February 11, 2014 Author Share Posted February 11, 2014 Wow, sweet..I could have used this a few times. My car pre-pathy never needed to press the clutch in to start it. Warming up the Pathy in the morning before work and having to climb in and clutch/start, jump out, etc. Reaching in the window will be easier, lol.

nunya Posted February 11, 2014 Share Posted February 11, 2014 It's the switch for locking the inter... what else would it be? (Yea, it just cancels the clutch safety switch so you can crank er over without the pedal on the floor) Link to comment Share on other sites More sharing options...
Precise1 Posted February 11, 2014 Share Posted February 11, 2014 +10 HP!! I never understood it, you can press the brake and clutch in almost any situation, then brake to gas while modulating the clutch. B Link to comment Share on other sites More sharing options...

B To me the only advantage of having the interlock switch is being able to crawl over obstacles without lugging the engine or causing unneeded wear on the clutch.

silverton Posted February 11, 2014 Share Posted February 11, 2014 (edited) You kill you engine a lot when crawling? B I have an automatic, so no I do not. It's not a matter of killing the engine while wheeling. It's being able to spin the engine at low RPM while still having the transmission directly connected to the engine. Too much rpm can cause a tire to just slip and spin, where doing something at a lower RPM can be just what you needed to get over the minivan sized boulder. Why put a second transfer case in a rock crawler? Because then engine RPM's can stay high while wheel speed stays low.

Precise1 Posted February 12, 2014 Share Posted February 12, 2014 We are talking about a clutch switch, meaning the ignition will not respond unless it the clutch pedal is depressed, ie. safety starting. The clutch in my first Pathy worked exactly this way. What does this have to do with low RPM? It only applies when you are starting the engine. Yeah, lower gears/wrok krawler/etc but that applies how? B Link to comment Share on other sites More sharing options...
silverton Posted February 12, 2014 Share Posted February 12, 2014 Right, and the interlock switch bypasses that safety so the truck can be started in gear. A starter is only going to spin the engine at around 200rpm, whereas if you try and use the clutch to obtain that RPM while the engine is running you're going to lug it so hard the pistons slap. Essentially, a built in crawler feature. He's asking what the switch does, and I'm telling him the intended use of it. Link to comment Share on other sites More sharing options...
Kingman Posted February 12, 2014 Share Posted February 12, 2014 Its useful for when your truck doesn't run and you need to move it around the driveway, or drive it around the block. Link to comment Share on other sites More sharing options...

So you are saying the reason the reason for the switch is to use the starter to provide locomotion when the RPM would be too low? That is the intended use? Just remove the engine and add batteries then, the perfect wrok krawler! Its useful for when your truck doesn't run and you need to move it around the driveway, or drive it around the block. Yep, I have pulled mine into the driveway that way before, a total of 30 feet. A come-a-long does the same job, just slower; I doubt that was their intent.

Kingman Posted February 12, 2014 Share Posted February 12, 2014 Although I will say this... if you don't have enough common sense to make sure its in neutral, unless you're intending to move it with the starter, don't touch that button! Link to comment Share on other sites More sharing options...

mikestewart395 Posted February 12, 2014 Author Share Posted February 12, 2014 You warm up your truck in the morning? Don't you live in Florida. Yes I warm it up. When it cold starts and the RPM's are not leveled I don't believe in racing off in it. I let the fluids balance out before I drive off. I am a firm believer this gives your engine a longer life. My dad rebuilt engines for classic cars for 40 years, it was a crime against humanity if he didn't let the engine warm up. I'm not talking about a 30 min warmup, just a crank, go put my shoes on, grab my coffee, then jump in. Link to comment Share on other sites More sharing options...
devonianwalk Posted February 12, 2014 Share Posted February 12, 2014 Might help with a remote start feature as well? Link to comment Share on other sites More sharing options...

silverton Posted February 12, 2014 Share Posted February 12, 2014 Might help with a remote start feature as well? Those systems are wired to bypass a starter safety if equipped, which is why it's imperative if you have one, you leave it out of gear when you plan to use it.

kdj Posted February 12, 2014 Share Posted February 12, 2014 At -20F I scrape off the ice, hop in, start it and go. 320,000 kms so far. I've never used a block heater either. Different habits I guess, my father would have kicked my ass if saw me idleing in the driveway for no reason. Link to comment Share on other sites More sharing options...
AndyC Posted February 12, 2014 Share Posted February 12, 2014 It's actually kind of in between what silverton and precise were discussing. If you stall the engine in a climb, and rolling backwards while going from brake to gas would put you in a worse situation. You can use the bypass. Left foot on brake, right on the gas, bump the ignition and give it a little gas, off you go. However in 7 years of wheeling mine I never once needed it. Did try a few times just for novelty.

Kingman Posted February 12, 2014 Share Posted February 12, 2014 (edited) Better for an engine to warm up as fast as possible so it runs leaner sooner and doesn't build up overly rich deposits. Just long enough for the oil to circulate is fine. Edited February 12, 2014 by Kingman 1 Link to comment Share on other sites More sharing options...

That has what bearing? You were still sheitting your pants when I was wheeling... I don't know the reason for it, I just know I never had any use for it and I'll bet it wasn't to use your starter as Wrok Krawler drive either.
