Ive noticed that my old solenoid wasn't working well. I ordered a new one and wired it up. I set my rpm screw on the summit switch all the way to the left. The green light turned on, and the solenoid kicked in. Problem is its not pulling open the mevi valves. I took a pic of my VAC setup. Also have a diagram of my wiring setup. I would appreciate any ideas of getting my mevi to work again.


CANISTER

SOLENOID

 

Why did you turn the screw all the way to the left(CCW?)

 

You should have left the screw where it was and set the switches to a lower rpm just so you won't have to rev high when you're tesing it. The pot is very sensitive to adjustment so try to set to back to the stock location.

Why does it look like you only have one hose hooked up to your solenoid?

 

Doesn't one of those hoses go to the soleniod and another one goes to the mevi? Im pretty sure that's how everyone has it set up other wise why are we using canisters to hold vac? Also I put back to screw where It 1st was. It was set all the way to the right. Instead of asking more and more question's can someone give me some valid information on what is hooked up wrong.

 

Bump common there are so many guys with mevis on the org. Someone please take 2 min to look at what I have and tell me why its not opening.

 

Are you saying you have 2 hoses hooked up to your solenoid? That is what you should have. If you have 2 hooked up and you can hear the solenoid opening then you probably just have the vacuum lines hooked up incorrectly to the solenoid. The MEVI actuater needs to see ambient pressure when the solenoid is in it's rest state, and when actuated it needs to switch over to see the vacuum from your vac canister.

 

I have one hose connected to my soleniod from the canister and then another hose that connects to the soleniod to my mevi. The solenoid kicks in I hear it but it the mevi valves don't open.. Im not sure what it is... But they why I took a pic of my vac setup and I even did a diagram of my wiring.

 

Ive been so busy you have no idea. Ive only had 20 min a day to work on my own car let alone a **** load of other things. congrats on your business. Drilling holes are a simple task brotha. Get a small drill bit, put some masking tap on the hood where you are going to drill, mark the holes and then go straight down into it haha. Ill do it for you, im busy tomorrow I have a customer that wants to come and pay me 150 for some silly simple stuff.

 

first things first. work on the summit rpm switch cause you can probably have all the hoses and wires set up right and just have the switches set so high that its not triggering the rpm switch to activate (a.k.a turning from red to green at the set rpm selected 5000rpm etc...) messing with that screw you might have it set too like 10,000 rpms thats why i say mess with that first to ensure you have tht working properly.

once you get the rpm switch working correctly turning from red light to green light everytime you reach the selected rpm that you have chosen then you move on to the hoses . let me know if you have atleast the rpm switch working right then i can let you know about the hoses. but here is a quick pic of my solenoid setup

 

Did you test that you have the hoses hooked up to the correct nipples on the solenoid or not? There should be 3 nipples on your solenoid, and 2 of those nipples need vac hoses connected to them, but they have to be the correct ones. You can't just connect the hoses at random to the solenoid.

 

Ah ****, I see where I might have fuked up, look at your solenoid laylow that one single nipple you left alone I have a vac hose to that and I ran it to the mevi thinkin thats the one that goes to the mevi... Ahhhh ****, Let me run outside and run my vac lines diff now. Ill take a better pic of my DIP switch box.

 

Damn, nothing worked. I noticed that I don't feel any air being sucked in my the solenoid. I feel the thing kick in. It kicks in at a certain rpm but If i exceed that rpm it shuts off.. Here is a pic of my dip switch settings.

 

I see a problem with your switches on both sides. You have 2 switches in 'on' position when your supposed to only have one of each. The switch will not activate when you have it setup like that.

 

It is a very simple vacuum and wiring process. You have had an MEVI for a long time now, how can you still not know how it works?

Tapped line going to vacuum canister. The larger hose is from the tap, smaller hose going to the solenoid

I know you can't see this picture for ****, but I took it so I am posting it. Only one dip switch is turned on for each board. You got a total of four switches on???? This isn't a harlan switch!

it seems there is no consistant way the switches need to be set to get a 5300 rpm activation. You just have to play with it till you get it. For me it is 6000....why I do not know. On my old summit switch it was 3400. Just play with it and figure it out

Hey, how did this pic get in there

At the very most you migh need to swap around the vacuum lines. You might have the lines going to the wrong ports of the solenoid or the vacuum canister. There are only so many combinations you could do. Try them all if you are not sure.

Also, make sure your canister is holding vacuum. After the car has ran for even a couple seconds there should be plenty of stored vacuum in the canister. After the car is shut off, remove the hose going from the canister to the solenoid. You should hear a rush of air. If not then it is not holding vacuum.

 

Damn, so a few of us do think alike on some things. I used tie straps to tighten my hoses to all of the vacuum fittings also.

 

hola coma esta? bien gracias y tu?

 

Thanks mike that really cleared it up. Im going to check tomorrow sometime about the dip switches. Your pic is really fuzzy. from what I see is that you have the right side boxe on but only the longer box has your opening settings. Am I correct on this?!

 

It is set at 6K and 000, but that probably won't be the same for you. Like I said just play with it and find a way to get it to activate at 5.3K rpms
