Alky problems again!!!

[attackdog]

I have the SMC kit and it is suppossed to start spraying at 10lbs of boost but for some reason tonight it stopped working. The green power light is on but at 10lbs it will not spray and no light (spraying). Is there a way to fix or troubleshoot this kit? Thanks.

check to make sure the hobbs switch is closing and sending the signal. first jumper it with wire, and assuming it works then check it with regulated air pressure.

this is all assuming the kit uses a pressure activated switch and not a 0-5 volt signal off the map sensor for activation.

Re: Alky problems again!!!

will it spray when you hit the test button?

I tried the test button but the "spray on" light did not come on. Do I have to be in boost and push the test button or can I just sit still and push it? Thanks.

Were is the hobbs switch located or look like? How would I know if it uses pressure or voltage. It was on my SY when I got it so I am pretty clueless on this kit. Thanks.

It should spray when you hit the test button. Start the truck, have someone watch the gauge and hit the button. You should have to bring up the revs to keep the motor from stalling. I'll bet the pump is failing and you show very low pressure.

I tested the pump with a jumper and it is working. What is my next option?

Re: Alky problems again!!!

which kit do you have,,,,,progressive(external pump) or nonprogressive(pump mounted in the tank)? How much pressure did it show(between 80 to 120 depending on system)? If you used a jumper and show good pressure then it's probably the pressure switch. Call Steve at SMC regardless. Even if the kit was used he has great customer support.

I have the non-progressive kit. I did not have anyone to help me so I did not get a chance to check the pressure. Also, when I used the test button, the truck bogged down like it should. Should the "spray on" light turn on when the test button is pushed? Thanks again for all your help Ross. Do you have a number off hand for Steve at SMC?

Re: Alky problems again!!!

The spray light on my SVO doesn't work either but it makes a solid 70-80 psi with the motor running when the "test" button is pushed. I always test it before getting into boost(25psi), it should "bog" the motor. I also have my daughter,neighbor,dad,hobo,dog someone push that %$#@ button located in the car while I check the pressure under the hood :rant: Why couldn't there be a "test" button under there as well??? Better yet a gauge you could read from the drivers seat. That would solve all of us "alcoholics" problems. :rotf: Good luck!

What would cause that light to stop working? Is it a bad bulb or sending unit to the bulb? If I replace the pressure switch, do you think that would make everything work again? Thanks again.

I "think" so... Call Dave Monday, he's very good to work with. I don't trust the light anyway, pressure is whats important. The light could work but you still have low pressure(I think it's triggered by a 30psi switch). Don't quote me on any of this. Best bet it to call him.

I used the test button earlier to check the pressure and it shows 62psi at the gauge. Is that were it should be? I have a feeling that my light stopped working. Bummer.

Re: Alky problems again!!!

that sounds about right for the earlier kits. You could apply 15psi to the vac. line running to the controller to make sure it's activating. Although with mine I always ASSume it will work as long as the test button works.

Re: Alky problems again!!!

I went out to jumper the pressure switch and it fell apart in my hand as I was trying to remove the wires from it. So, I guess I need a new pressure switch. Crap! I don't supposed you have one laying around that you want to sell do you? Thanks.
