Have you for sure concluded that the cluster is bad Smutty? I know you've had issues with certain things not working including the temp gauge but the whole cluster has went bad?

Smutty let me look the wiring diagram over on this scooter and I'll get back to you. I remember you said the fan wasn't working also right? I'm sure just like with a lot of scooters this system has plugs the male to female type and it sounds like a loss of power to a very bad connection or loose wire?
Can you list each item that does not work? Again I'm going to look at the diagram and knowing the things that don't work for sure will help me a lot.

Smutty , is that dashboard all digital ?
Can you post a pic of it , I don't know what it looks like . If you can take good pics , That would be a great help .
How are you doing with that new meter , Have you been able to post a pic of it or post a link of it . If you can't post pics it will be hard to instruct you on how to take measurements . Come on dude help me help you .

Yea I read that, kind of funny one who has a Cf Moto listing the diagram instead of a diagnosis and another who sells them sending him to the manufacturer. ;D From what I see even if though this is a digital dashboard system it still is individually wired to each function. Also the fan can be trouble shot and corrected too. It was built so it can be fixed. JR |

well I saw and read this post . I wonder if the grounds are good . The 5a fuse to the fan . I suspect he may have lost a power line (VCC) like on an amp it energizes the electronics . This is not shown in the diagram . The digital display has to get power and ground , I'm not seeing that either .

The fan is simple, it has 12vdc from the black ignition wire all the time. The thermoswitch in the radiator closes the ground side when the switch closes. These switches are famous for going out.
Two things to check, turn the key on and see if you have 12vdc on the black wire to the fan plug. If so then unplug the two wires on the radiator thermoswitch and put them together, the fan should come on. If it doesn't and you have 12vdc to the fan with the key on then the fan is bad.
If the fan works when crossing the two wires from the thermoswitch then start the scooter and let it come up to temp and place the meter leads on the thermoswitch terminals and watch to see if it closes for full continuity, if not then it's bad, replace.
I'm looking for info on the instrument cluster and will get back.

Smutty you've done one good piece of discovery by confirming the fan works so that's a good start. Let's fix it right as a toggle switch leaves room for human error as in forgetting to turn it on and it's not necessary to run it all the time. Now getting the stuff out of the way to get to this switch is a good thing to and I want to add that sometimes it's just a dirty or bad connector on the switch itself that can be the problem. So again when you get to the thermoswitch pull the wires, turn on the key, touch them together and if the fan runs then let's go to the next step. NOW REMEMBER one of those wires goes to ground and if it's not getting a good connection then the fan won't run. The thermoswitch completes the ground side of the circuit. So if it doesn't run then then take a jumper wire from the negative side of the battery and touch either one of them and see if it runs. You cannot mess anything up here so relax. If this happens then you need to trace out the ground wires and fix the problem. Now if the fan runs with just touching the wires together then let's test the thermoswitch. With your volt meter set to ohms then put one lead each from the meter to each terminal of the thermoswitch and start the scooter. Let it warm up good may take 15 minutes or so. Since the temp gauge doesn't work we'll be in the dark but the thermoswitch usually strats closing in the 160F + range and when it closes it will then read 100% ohms resistance or full continuity. If the fan runs with just touching the wires I'm betting a bad thermoswitch but the system could have air in it and need burping which can cause a switch to not close but we'll cross that bridge when we get to it after these tests. Posting pictures here's a guide how to: thescooterprofessor.proboards.com/index.cgi?board=directoryI've also made some contacts about this cluster and will get back. JR |

Alright Smutty! We're gaining some ground on this. Now just checking for bubbles is not the real way we know if there is air in the system and since we don't have a working temp gauge then we can still do this to see if it could have any air so here is a simple step by step.
(1) With the scooter cold remove the radiator cap check to see if it needs coolant add 50/50 pre-mix if needed, I prefer Prestone
(2) Leave the cap off and start the scooter and let it idle for a couple of minutes, watch the radiator and see if the level goes down, if it does then add until full, immediately put on cap and then fill reservoir bottle to the level it's marked to fill at.
(3) Let the scooter idle until nice and hot say at least 20 to 25 minutes.
(4) Turn off and go watch TV, read a book, etc. but let the scooter totally cool off bone cold.
(5) Remove cap and inspect to see if it's still full and to see if the level in the reservoir bottle is still ok too.
If this all checks out then do the thermoswitch test again in fact hook the wires back up and fire her up and let her get good and hot and see if the fan will come on. I don't know what your temp is where you live but it's 60F right here now and it should warm up enough for the fan to come on?
If it's very cold where you are at then your only choice is to remove the thermoswitch and test it in a pan of hot water again needs to be 160F or hotter. This also means draining the radiator but if the switch is bad you're going to have to do this anyway?
At least we're on the right track to one of the problems and hopefully we can fix all of them.

Yes Smutty the black wire from the ignition feeds a lot of things including all the functions on the cluster. It is hot when you turn the key on. The red wire from the battery goes to the igniton key switch and with the key on 12vdc feeds down the black wire. You need to check each fuse with the ohm meter, just because they look good means nothing. If a fuse is good then it will have full ohms resistance.
When you said you had tail lights with just the key on then the instrumant lighting is on the same circuit, I'll look again but I believe that from the headlight switch its a brown wire that feeds the tail lights and instrument lights. So it tells me that its highly possible that you've got a bad connection on that circuit and lots of times it a plug od some sort.
You're starting to undersatnd this and go to the tech section on Chinese manaulas and look at cfmoto and print out the Fashion wiring diagram and it'll help a lot.
Hang in there we are here to help.

Ok did you send them to my yahoo email? I'm going to be out for a little spell but will check back in later today.
Yes that is great news and it tells us there was air in the system and just the smallest amount of air will interfere with the fan system so good job. If it took a spell to come on then I'm presuming where you live it's not very warm? If you ride this scooter in cold temps a lot of time just the air from going down the road will keep the fan off but like you said we don't know the temps so next is trying to figure out the gauges.
I'll check the email afterwhile and get back.
Can you just for reference list all the things on the cluster that don't work?
Most people use photobucket and download to proboards and it's free.
