Rev counter working sporadically....???
Rev counter is working on and off. I know people have had this issue before so if you could let me know the remedy it would be great. I assume it may be the contacts on the back of the instruments so if someone could confirm that it would be great before I dismantle the bl$%dy thing!!

Not sure if this is the same thing, but twice in the last 3 months I've spotted my revs firmly at zero whilst driving along, but a tap of the plastic screen brings it back to life. It's not dial-peel, so I assume some form of loose connection starting to happen either inside the guage itself or on the PCB to the rear...

Hi Dragon,
That's exactly it. I am meaning to do the solder points on the connectors but in this weather I can't be arsed. I am sure it is definitely that. Main problem at the moment is my rear demister which I must set aside a couple of hours to check all the wiring. It'll save all those half hours waiting in the morning!

several reasons. most obvious first.
1) the cracked connectorpin weldings.
1 a) green connectorpin connection
2) the magnetically shielded gray speedo wire that is brittle (make a d tour)(for the speedo)
3) current peaks. I saw people having more trouble as there is a low voltage
4) sensor failure

That's typically called an "engineer's fix" and is a perfectly valid way to repair TVs, PCs, Cars and pretty much anything

He he - at the risk of getting you back up John (not intended), I seriously doubt that you knackered your HDD by hitting your computer, unless by hitting it you are REALLY whacking it, or picking it up and dropping it on a hard surface, and even then, it's unlikely to damage a HDD unless the heads were on the platter at the time.johnd wrote:Peter,
Don't hit your computer....you'll knacker you HDD. Speaking from personal experience here!!
John
Modern drives (I mean any drive made in the last 7 years really) are made to withstand shocks of between 5 and 8G, thats a hurrendous amount of force to generate that. The heads autopark within a millisecond of finishing a read/write phase, securing the head and arm out of harms way of the platter.
I used to work for Escom, making and repairing PCs and we all hit computers at time to time as part of the diag routine, and we never broke a disk (or anything else) doing it.
I suspect your HDD was probably on the virge of death already, unless you really did whallop it whilst it was on and in use?
