Dash wiring problem - Ski 206 2006

[Stu]

I need a wiring diagram for a Ski 206 2006 dashboard. My tack, volt, fuel, speedo all are acting whacky. The speedo trim pot was rewired by my dealer and they say they do not have and cannot get a schematic.
Love my boat. Please help.

Which model is your 206? I've got a 2005 se, and have recently had the dash apart installing Perfect pass and moving my speedo. I have some before pics that I could share if it would help.

Yes your pics would be really valuable. I'm sure that I have a bad connection/misswire by the dealer. The speedo pot only works over the first 1/32 rotation. The vot meeter reads low as does the fuel guage. many thanks

The diagram could be completely different depending on which model you have. Is the boat a Signature (keyed ignition), Limited or Team Edition?
If your boat is a Limited or Team the wiring all runs back to the Gateway box in the trunk, you could simply have a loose connection(s) there.

I have a good old fashioned keyed version so it must be a signature. No Perf Pass, etc... It's just a great boat excepting for this issue.

check your grounds

Pm me your email and I will send them to you, but most likely you have a loose wire.

The tach has a grey wire that feeds it the signal and goes no were else. The speedo has a 3 wire harness that is dedicated to it, they pretty much all have a common power and ground that starts at one side and jumps to all the gauges, it should be a purple wire (was on mine). There is also a light circuit that is jumped across all and a ground for the gauges and lights that is shared.
