Good for you. Keep that a goal in your life. When I was young I did way to much partying. It is a dead end street with nothing but much more frustrating problems. I have not consumed alcohol for 22 years now, and do not miss it.
BK/WH is 86.
R/BK is 85.
These top two as listed are your coil. One should have a hot. The other side would be triggered by a ground from pcm.
LG/BK is 30. This one would have the Battery positive and or the heavy load.( Now after saying that, a ground could be used for what ever)
LG is 87a I clearly do not think that should be hooked up in this application for it would be hot all the time.
LG/Y is 87 this one should be hooked to your fan.The bottom relay should be the same. I really question why the X is on the one tab 87, because from what I see it should be on the one below it. (87a will be hot through 30 all the time when the coil is not energized)
Take the relay out, hook a 9 volt battery across 85 and 86. It will not make a difference of positive or neg to either one, it will not care. You should feel that coil when energized switch contact between 30 to 87a then to 30 to 87. (continuity)I will let dreamer respond to that for I have not looked at your wiring diagram as of yet.
Are you sure you have the right relays?O.K. just had a few minutes to kill. I see the Hi speed fan relay does feed to your Low speed relay when Hi speed relay is not energized. So disregard my thought on the relay that uses 87a and 87. 87A is feed to your low speed relay.
Lovely valve seats in the Ford 1.9 and 2.0 SOHC engines!
In your voltage drop, you will be reading millivolts of voltage. You should hopefully see something like .123 . That period before the numbers is correct, or your meter will show a mv in the screen if it does not show a period.
I did not read your other thread, but I am wondering did you change the relay? Pull your relay out and take a 9 volt battery, hook up to your coil side to fire relay, at same time have your DMM hooked up in ohms to measure resistance across the 2 terminals that would feed power to fan side to see if there is resistance on the points of the relay.So from what I have seen so far , you are left with either pcm is not grounding the relay or, a bad wire going from relay power to fan.
Can you ground the coil side of the relay manually to get the relay to fire? If you can, then will the fan start?
If you are not able to get in there to ground it, make 4 jumper wires with connectors on them (sort of like jacking up the relay so you can see) and plug every thing back together so you can physically ground the ground side of coil.Did not have time to watch all, our IP has been having intermittent problems.
You probably have a hot wire constant to coil, either #85 or 86. You say why? One side is hot and that feeds through the coil looking for a ground. That is why it is hot on both sides.
On # 30, it should be hot also. It is waiting for pcm to give a ground to either #85 or 86.
I could not tell if that was a 5 wire or 4 wire, but looked to me like a 5 wire relay, therefore # 30 is in direct contact to #87a and will remain hot untill the coil finds a ground on #85 or 86. At that time when coil is fired, #87a will be opened and #87 will be hot. That is when (and the wire) that should feed a hot wire to your fan.Next step unplug relay from connector and then find which one is hot of terminals#85 or 86. When you see which is hot, make a jumper for the one of the 2 that is not hot and ground that side to fire the coil. I am doing this in a hurry, have to head to work maybe some one will catch an error here for me to steer you in right direction from here.
With that compression, I would say alcohol!
Alcohol engines are designed to be high compression. That is where you get the bang for your buck in performance out of the lesser BTU’s. You also will have to change timing with it for the most performance. Gas has a problem with to quick of detonation therefore losing very valuable energy, and that is how ethanol or alcohol can stack up to it in a proper set engine.Gatiszvejnieks, thanks for the info. I am still in thoughts about the subject, probably could afford to do parts swapping on my own stuff for the short time.
I would not drive it in dirty, or rainy conditions that way. Glad to hear you have it resolved.
No such thing as a stupid question, only stupid answers!Quoted From Trcustoms719:
Your only as old as you feel, if you think your up to it then go for it!
That, some mornings makes me the oldest man in the world!!!
I am 3 years younger then you. My question is how is your back and knees?! If you have a desire to do it,why not? We will probably all have to work untill we are 90 before we will have a retirement coming up here in the future!
