Apex error 1 code

[dmaxx]

06 Attak. Noticed warning lights riding and pulled over. Engine symbol, temp light, warning light and error 1 on the bottom of gauge. Noticed a 64 code a couple of times. Checked all coolant etc, not overheating. rode and it went on and off, flickered occasionally then stayed on. Noticed tach and speedo did not work. Even an error 2 showed up when I turned the key on then disappeared. Tried disconnecting wires in boot, unplugged speedo harness, tried to reset no luck. Code list shows short or open circuit, no signal from ecu. What are the chances ecu is going or more likely wire issue. Have a ride next weekend so I have to find quick. Any help appreciated. Pic attached of gauge,

Have you tried unplugging the speedo gage and plugging it back in? Maybe it's a loose connection somewhere else. Battery fully charged?

Did that several times. Boot was loose and I blow dried the connection and harness. New battery, tried unplugging battery connection, no luck.
Should mention that sled ran fine, no issues. Could not adjust hand or thumb warmers, they came and went. Just before we finished, speedo flickered, tried to work but did not. Read posts on driveshaft bearing, it looks fine. Cant get diagnostic mode to come up, can only adjust the gauge lighting.

Found this broken wire on top of rectifier.

 

[steiner]

That would do it.

Error code still on, now flashes err 1 then err 2

Fixed rectifier wire and still showing error. What could the chances actually be two issues at once??? Searched old posts and most point to gauge cluster. Ran fine otherwise would there be any harm to run other than not knowing if engine gets hot?

check your driveshaft bearing under the Secondary clutch. same thing happened to me this past weekend. if you tip the sled up and give the drive shaft a good shake you can tell. also check the speedo sensor as well, when the bearing gets real bad it will hit the sensor and damage it.

 

[dmaxx]

Not the bearing, all is goo0d down there. Looks like gauge cluster according to other old post.

does anybody know where the crankshaft position sensor is . I have a code 12 . I like to test it.

 

[maxdlx]

Search code 12. There is a post on how to fix it.

Thanks for the reply maxdlx.

sounds like you have ground block isues to me.

 

[henseljg2]

Yes. I bet $$ you have a ground somewhere. I had a bad ground on a POS that i acquired that got left out in the rain all summer under a pine tree. Had a ground, threw the er-1 code which eventually fried the ecu. Ended up replacing the wiring harness and ecu instead of taking any chances with it.

I've also seen a ground in the speedo throw the er-1 code on a vector.

Installed new gauge cluster and error codes and warning lights are gone!
