dimming lights, electrical diag

[QuimbyKat]

okay so I let my wife wash my bike with me and boy was that a mistake, now I think I have some corrosion problems... The kat will intermitently have the tach and speedo stop reading and drop to zero, the back lights on the panel will dim along with the headlamps and singnals (not sure about the brake lights but assume they do too) I'm thinking it's power but I haven't opened her up yet, so I was wondering if anyone had a wiring diagram for a 2006 Katana 600 so I could do some circuit analysis... And also some opinions on what ya'll think...

Check your connections, wiring diagrams have been posted several times. Use search. And as an extra hint... I'll let ya know that it is in the service manual.

my apolo-geeze... I posted on the run, but I was hoping for some direction from the peeps here at KR... Such as maybe people who have had the same situation...but I've started running down the connections I looked in the cluster for water damage but found none... So far nothing...

I havent had that problem personally so I dont know where to point ya on that one. I dont have traditional gauges on my kat.

Water has likely made it's way into a place it shouldn't be; bikes are OK in water but when you spray water up into the area of the harness and battery, you are defying the intentions of the factory water-proofing, which is designed to deal with normal precipitation patterns, not total submersion. You need to 'open her up' as you say.

Start at the source; the battery. Re-seat your battery's positive and negative terminals, and the ground. Begin working from there toward the wiring harness; disconnecting and re-connecting where applicable. Don't just visually inspect everything either. You may not be able to simply 'see' the problem.

This worked for me when I had a similar problem on a '99 'busa.

there must be a open wire somewhere, maybe a loose connection.
