Bongo Fury

Rev counter behaving erratically has been fluctuating then dropping to zero which is causing the hold light to flash having looked at the bongo fury fact sheets I did as suggested and bridged the two terminals on the diagnostic block which resulted in a code fault number 6 which is output speed sensor. I am confused and would be grateful of any suggestions because according to fact sheets and all the posts I have read it is normally the speedo that drops to zero. If it is indeed the speed sensor does anybody know where it is located in the gearbox and where I could purchase one. Any help or advice would be greatly appreciated as I need to sort this fault asap as we are travelling to Ireland in it for a week at Easter. Thanks in advance Jay

the speedo chip that some people attach at the back of the clocks can cause these types of faults,check if yours is fitted with one.

I don't have a speedo chip fitted but why would this interfere with the rev counter? I don't have a problem with the speedo it is the rev counter it drops to zero and hold light flashes!

Don't know about the Bongo but some cars use
a led system to read the revs of the engine usually
from the flywheel, if they give problems a wipe
with a clean rag often fixes it maybe the Bongo
is the same.

ok thanks will give that a try

Mine used to do that i changed the throtle positioning sensor (under the drivers seat) mine had 466 on it. Just try some spary contact cleaner first to see if it makes a difference.

will try that right now and let you know how I get on Thanks

When i disconnected the temp sensor connection for the glowplugs the revcounter and hold light flashed. Maybe best to give the wiring connector blocks a wiggle/clean

will try all suggestions thank you very much bit dark now so will try tomorrow
