High Idle Switch (non-electric)

[Dfuruness]

Hello all,



I have just registered and I am very confident about the positive information that is available on this site.



If someone could provide me with some advice. I am curious as to what would be the best non-electric high idle control device solution available on the market? Like most, I am tired of using the 'foot to pedal' method of maintaining high idle during warmup. I have a 1995 2500, 2WD. Everything is still stock.



As you could understand it gets quite cold up here in Alberta, Canada!! Advice please...



Thanks in advance...

I don't know how non-electric you want to get.



Harold Bowers make a kit he sells that includes a selenoid that, when powered, will hold the throttle open. It works great and is very fairly priced IMO. His email is -- email address removed -- He also had a writeup on page 146 of TDR issue 33.



Obviously it is electric to function, but it still maintains a mechanical high idle. It is either on or off, it is not variable like some of the high idle kits for the 24v.



The other option is to hook up a manual throttle cable to the throttle linkage, or the go pedal. You can buy one at www.awdirect.com or NAPA



Hope this helps,

Ryan

Don,

Truck stops sell a universal "high idler" that works for around six bucks. I'ts a chrome plated rod with rubber inserts and a spring loaded, sliding adjuster. The rubber foot rests on the accelerator and the sliding adjuster under the dash. It's little more that a stick/prop thats easily adjustable. Simple and effective. Me, I just idle with my exhaust brake on.

A wooden dowel wedged in-between a power seat and the pedal makes for an cheap, infinitely adjustable idle control. I personally just wait for the intake heaters to shut down then drive, but I'm usually dressed for the cold and have been known to drive with the window down at 20°F. Most passengers don't like this though.

control cable

I have the NAPA cable on my truck pn#731-1103 and it works for me cost 21. 99 only one of many options

This is also a project I have on the waiting list. Im not sure if Im gonna go with a 12v solenoid, or wait til I have auxilary air from the air horns and use a pnumatic actuater. I was also considering designing an idle control circuit that will cycle 5 min of high idle then 5 min of exhaust brake engaged to keep the engine entertained if I decide to leave 'er run for a while. Gotta get the brake first though... . hmm, this could take some thinkin!

Just a thought!!

I've been kicking this one around in my head. Power window acuator an some spring loaded linkage.

Or is there a way to bomb the cruise control accuator.

 

[illflem]

jodog, yes there is a cheap, simple way to modify the cruise control servo into a rpm controller. I started working on it earlier but never finished. Read about it here https://www.turbodieselregister.com/forums/showthread.php?s=&threadid=6255. The thing that hung me up was finding the connector plugs for the vacuum actuator since I didn't want to hack up the stock wiring, but I proved it does work.

Don,

If you want a cheap non-electrical fix, I took a 3 ft pc of 1 x 2 pine stock and cut it in half. I then used duct tape to attach an old camper turnbuckle to each piece. I start my truck and then wedge it between the seat frame and pedal. It is very easy to adjust, just a turn or so, to get the desired idle, and it's adjustable. I can get the exact RPM that I want any time... I live in ND and I usually start my truck and put this on to idle around 1000-1100 for a few minutes while I go back inside. This is NOT my idea, I got it from another member on the TDR--It's amazing what you learn here... ...

Thanks for the excellent advice guys. I went with the NAPA part and it works great... .

My ice scraper and snow broom combination stick fits between the seat and the go pedal. I set the parking brake, drop it into drive, and nudge the idle up to 750-1000 RPM. It warms the engine AND transmsission.



IMHO, idling an unloaded diesel only serves to circulate the oil, cylce the intake heaters, and charge the batteries. It doesn't do much to warm the coolant.



Dropping the fan is a great way to defeat winter. I took the suggestion of many TDR members and only wonder why I didn't do it before this year.



Warmly
