It's 1990 rd690 w/ e6-300 has fan clutch  not not way to wire a switch on it 

Can u post a picture or two ?

Just two screws to the switch,I’ll get some pictures tomorrow, thanks.

I found a little time to mess with it,now I’m more confused than ever,Dash switch has voltage and works fine,clutch switch has voltage so I jumped the wires to by pass the switch,now down at the pump switch I get voltage on the one wire when the throttle is opened and when closed it shuts the voltage off,to further confuse me the two wires going to the heads are grounded,how do you get voltage thru grounded wires?

Jack it up and see if the wheels turn..🤷‍♂️

Did somebody mention Boobs?

Beautiful truck,doesn’t look to rusty to me..🤷‍♂️

Congrats Other Dog, enjoy your freedom from work,I hope to be joining that club very soon also..

Cool vid,interesting..

this question Joe asking  is important! older trucks used a Relay on the dynatard system!

Just sayin

It’s a Dynatard on a 1996 e-7 mechanical engine.

I think that the highlighted bit above MAY be your Problem..

 

For your Jakes to work that switch's contacts need to be Closed. Which is what the Clutch pedal holding the Springy thing Does. With that Broken Off I reckon the Contacts are now Open..

 

I'd do what Swishy Suggests & make up a Little Jumper wire & bypass the Clutch Switch. Or just Hold (Or Tape) the remains of the little lever Down. & see if they Work..

Thanks,with the spring broken the switch is in the on position,also I did jump the two wires and nothing,l should of checked for voltage at that switch also but I didn’t,now hopeing the problem is in between the dash switch and the clutch switch because forget about tracing the rest of the wires,they go thru the harness..

i beleive it goes to the clutch switch first then to the inj. pump. Is yours "full mechanical"? where is power missing? also. is it jacobs 680 brakes or dynatard?

Ok thanks,I have to start over and see if I have voltage to the clutch switch first,will report back in a few days..

is there a fuse for it? is there power to the dash switch ? 

Fuse is good,voltage going to switch on dash and leaving also,no voltage going to switch on pump,the springy thing on clutch switch is broke of so that switch is activated always,where does the voltage go first pump switch or clutch or both at the same time?

Can anybody tell me how to trouble shoot the engine brake on a 96 cl E-7,switch on the dash is working,I jumped the wires going to the clutch pedal switch,nothing,should one of those wires be hot and should one of the wires on the pump switch be hot,I have no voltage going to the pump switch..

So when you remove the fuel filters, the fuel is low in the filter?  Have you looked at the fuel lines from the tank to see if fuel is bleeding through them? I assume you checked the lines from the filter pads to the lift pump? There should be 3 lines and a #12 line that comes from the tank.. jojo

Thanks ,gonna check it all,I'll find it,I hope..lol

Oh well my problem still exists,started hard again this morning. .

Check all the plastic return lines to the head and the little jumper between the head as well, also have your oil sampled for fuel the orings on the injectors can be an issue! just another place to look if all else fails!

Just found a leak on the return line that goes to the front of the head,cut it back and reattached,I'll know Monday morning if that was my problem..

I am having the exact same problem on the exact same engine,I replaced two fuel lines so far,gonna do one more,if that doesn't work will swap out the lift pump..

Stay strong,you got this..🙏🏻🙏🏻

I like being on roads where there is  nowhere to stop. Crossed the Chester bridge one day a year or so ago heading into Illinois, and DOT was sitting in that little welcome center. Pulled out behind the line of cars behind me, hit his lights & started passing...so I slowed down to let him by before approaching traffic got to us. He pulled in right behind me...so I stopped. Right there blocking the road, halfway up the hill, with a rock wall on both sides of the road & zero shoulder. He had to get out of his car & deal with me right there while we were blocking traffic on the narrow 2-lane. He wanted it. He got it. I've done the whole "I know there's a big gravel lot 1/2 mile up the road, so I'll just pull in there where it's safe" and it didn't buy me an ounce of professional courtesy. Nope. The instant I know they're wanting me, I stop. Right where I am. Don't care if it's safe or not, because they've got the lights on their car & badge on their chest to protect them. He had to get out of his car, walk up, and talk to me right there directing me to a "safe" place...and of course I played dumb, until he said "just follow me" ...so he had to walk back to his car, pass me, then traffic could move again. It was fun. He had portables & weighed my steer...then did the math based upon my scale ticket to determine my drives were OK...guess he didn't want to dig out 2 more pairs (drives & a tag). Got a warning ticket for no spare fuses...he would've kept looking 'til he found something, so I figured that'd be the simplest & least consequential item to get a warning for. Soon as I didn't produce any spare fuses, the inspection pretty much stopped. He filled out the paperwork & sent me on my way.

Wow,never heard of anyone being asked to show spare fuses..

A lot of people pull the spacers out on them, they feel more like a race car but blow lots of smoke until they make boost

Did it clean the smoke up on yours ?

I worry about getting put off the road with smoke, it hasn't ever been a issue, but I never know when I migt have someone complain and to me it is a source of pride to have my yruck running as clean as I can and always been well presented 

I guess that's a bit old fashioned 

 

Paul

Here in NY if the DEC sees smoke your ass is going to court and you have to bring proof that it’s fixed and re inspected,besides all that smoke = soot in your oil,not worth it..

Check all your fuel lines on the suction side,just a pin hole is all it takes..
