My $500 gamble--Fleet washing rig & I dont fleet wash

It looks like there is a gearbox but I can't see a clutch from the picture, do you see any wires going to the gearbox?

After seeing your explanations yesterday, I had gone and looked for a clutch and/or throttle control. There are NO wires going to the gearbox, and thats when I figured out what that solenoid/actuator with the throttle cable was used for. So its definately throttle controlled, no clutch, so I will work on that sometime today.THANKS you are making this too easy!!

The unit does have a gear box so there is no clutch to disengage the pump. The switch should be a start stop switch. You can open it up at the gun and see if a wire is disconnected. Otherwise I would check at the machine and see if the wire to the grounding lug for the kill switch is off, it could also be a bad relay.

Thanks Paul--I just came in from lookingnat the setup. Here are pictures of the relay, solenoid and cable. Which would you put money on being the problem looking at the pictures below?? Yeah me too a frozen cable, I dug this one out from under the pump and water hoses. So far so simple but I will definately check the electrical operatioon of the relay tonight to be sure. first theres a few golf balls with my name on them.

Sounds like you won't have to put much money into getting the system working, that is great.

Keep up the good work.

Normally the 2 step systems will have an on off at the gun because just throttling it down won't stop the flow. That one may be set up different though.

That cable is obviously a problem and needs to be replaced.

you are right even when I manually throttled down the engine, water was still flowing out the gun. when say on/off switch, do you mean with the key on, i may be able to shut down and restart the motor from the gun? or is it just shut down as in grounding the coil or activating the fuel cut solenoid(i saw written it has one somewhere), and then I need to go back and restart(crank) with the key?

no, there are 2 switches at the gun one is for soap it is a three position switch one way is soap the opposite way is acid and the middle is rinse. The other switch should be a momentary contact when you push it all the way forward to start. When you let it go it will stay in the middle as run and pull it back to kill the engine.

Thanks for all the help with this! I understand the whole soap setup, and am trying to get this other switch and throttle actuator working. I took the switch assembly out of the gun and the run/stop is just a 2 wire switch with only 2 positions,a/b or on/off, and it works and has power up to the switch and the when switch closed, sends power to the relay. Now this is where I need my next help in understanding.
In the picture below, the relay, the 3 wires on the right side, red-white-black are the ones going to the actuator. The Black is a permanent ground. the red gets full time power when the switch is activated, and the white gets a 1-2 second power feed every time the switch is cycled. Im not sure of the operation of this actuator, does anyone know the power/ground sequence to make this work? and why the temp. power of 1-2 seconds on the white wire??
I have an email into Red-Arrow looking for a new actuator as they manufactured this unit--but am working on it tonight and was trying to wrap my mind around all this.

good buy o'brien. i love picking up old equipment like that.

Yeah I love playing with things like this!! The great part is there is no pressure to "get it done now". I just want everything working perfectly, then I am going to tear it down, repaint and clean everything, and replace the wooden floor on the trailer. The wood floor has a sheet of diamond plate covering the whole thing, but in the back under the water softener tank, 2 of the boards are rotted. no biggie! Its a winter project for me.

Got thru to Red Arrow and $150 later I have a new throttle actuator on the way. Pricey little sucker but gotta have it. Getting closer to the teardown time. Still havent figured out all the valves and plumbing for tanks and water softener options and one at the pump box to.

The transformation began today--totally tore down, cleaned frame and tomorrow will start to repaint and rebuild.

Are you going to re-use the diamond plate with wood under it? If that is 1/8" DP, it weighs approx 6.5 lbs a square ft. You could save a lot of weight. I am guessing 1/8". The weight is approx as my book is still packed away.

Good luck

yikes I knew it was heavy but didnt know it was that heavy. That explains the sore back. Yes the diamond plate went back on the trailer. I am repainting everything red, as my landscaping trailer is red and want to stick with the same color theme, and my truck is red and white. I repainted the lower part of the trailer today, installed the new wood floor with pressure treated wood, put the diamond plate back in(with 2 other guys) and painted the diamond plate red as well. No pictures today as it was dark when gave up for the night. all is going well.

Great find Tom!! Still need to do the lunch thing sometime....maybe after Turkey day!
