Tip for diagnosing failed 355 speedo sender

My speedo/odo stopped working tonight...so I read all the threads that say if the sender fails, your suspension light will come on. Well, my suspension light was NOT on. So I checked all my fuses...they were okay (well did find my left hand radiator fan (30amp) fuse was blown, replaced that...now working fine (funny, never noticed, and car never overheated)). So...I went for a drive to see if the replaced fan fuse had anything to do with it...nope. Returned home, and cleaned the connector plug at the sender, and treated with Stabilant 22A and went for another drive...nope, BUT now the suspension light came on! So, three starts, and the suspension light came on....I seem to remember that with some of these computers and such, it takes a three or more faults before the lights come on, to ensure it is not a temporary glitch...so remember guys, the suspension light may not immediately come on..but after a few start/stop cycles...it will. So, I just ordered a new speedo sensor from Daniel at Ricambi America...should be good to go in a few days.

Bye....
