Have I Blown My Instrument Cluster?

last night i took out my instrument cluster to replace the fugly blue led's i had with red ones.. anyway, i have a quick release boss kit for my steering wheel which i took off to make getting the cluster in and out easier, that left the horn button exposed as well as the ring around it which completes the 'ground' (i think) cicuit for the horn.. the 3 plugs at the back of the cluster where as usual a prick to get off and in the process the back of the cluster tapped the horn button and maybe the ring at the same time, which produced a flash and immediate constant beeping from the dash.

i got worried and wanted to see if i'd rooted anything so re-plugged the 2 i'd already taken out back in to the cluster.

long story short.. my cluster lights all work, and the fuel gauge is active, but the rev's, speedo, oil pressure, kilometre counter and the triple gauge cluster are all inactive, but they do all light up, just no actual movement.

also when the cluster is plugged in there is a constant beeping from the dash, which will only stop once i remove the centre white plug..

i think ive fried some of the circuitry in the cluster itself though visually i couldnt see evidence of this. has anyone ever had something similar happen? anybody know what it could be? the only way i can think of finding the problem, is trying another cluster to see if it works, if it does than ive fryed mine, if it doesnt work, then ive just blown a fuse somewhere, or worse the computer.

dont know if im posting in the correct thread but this seems where all the electrical questions go..

im really keen to get this fixed as id had the car apart for some time doing mechanical work and an intense interior detail, and this was the final thing to do before i could drive again. so im spewing that ive got to deal with this now.

any help is as always hugely appreciated.

cheers guys.

Unscrew the back of the cluster to get a better look mate, you will soon see if there was any damaged caused. It sounds like you have fried something but to what is hard to say without having a look at it.

i took off the black cover that you see in the photo. but no damage was visible..

do you mean take off the black plastic cover then completely disassemble the thing? i was thinking about it, but didnt want to make it any worse.. but seeing as its not working anyway, i might do it tonight.

Yeah mate remove the black cover and expose the circuit board the best you can to see if you have burnt/damaged any of it. Id say that you have and that's causing the "beeping" but whether or not it can be repaired is another thing.

      Well, fun day was had, I finally found a house that will do me just fine, 1980's brick build, but with full fresh renovations, plus new colour bond fencing all round so puppies are incoming 🐕, and water tanks for the garden, and it's located in West Goulburn..... @Duncan 🫡, so day trips to Wakie to watch cars going Zoom will be on the cards In the end it cost well under my budget and was actually better than alot of the more expensive joints I was looking at, it is in a good area, close enough to the shops, public transport, and the Wollondilly River Weir,  and the great walking paths along the river, but far enough away from town to see minimal traffic The deposit is dropped, the conveyancer is conveyancing and I should get the keys in a week or 2 as the property is currently unoccupied  As with everything I own, I'm doing up a modifications list, as it doesn't have solar, that is first up on the big list, all of the panels and enough batteries to keep the joint warm, or cool, followed by a largish carport out the front, the small list, which will start as soon as I have keys, is some security stuff, like cameras, screens, and the usual "crazy prepper" additions that weird old people like (mouse holes to stick shot guns out of, and the usual man traps that the average person installs for the unsuspecting and unwanted guests 🤣) The gardens front and back are OK, but, not to my standards or liking, so landscaping will be a fun job to start getting into, so when spring is sprung I'll do a heap of planting, lots of natives and vegetables is the plan, the old owners were more "Old English Garden" type, so basically Roses and other weird looking things that are destined for the green waste bin One thing that is staying garden wise is a nice established hedge out the front, it is about 5 foot tall and covers the whole front of the property from prying eyes As for the car hoist, the roof in the garage has some height to it, but, I'll need to get an installer out to see what can be done, width wise may be a issue, but my building inspector will be getting back to me over the next week with his recommendations  Small, but cosy

      I tried to get in contact before I went to QLD you didn’t respond, then I tried to contact you in r31 club.  I thought you fell off the earth or something haha.  I will grab it off you but unknown when I will be up that way

      I think that might be in the question. He is going very low, and I think the standard GTR ones are simple tripod joints (like the rear NA/S chassis ones), not proper CVs (like R chassis turbo/GTR ones). Proper CVs take the misalignment better than tripods.

      Do you still need the wiper motor and stuff?

      I haven't used the Crank Motorsport ones, but can I ask why not use standard gtr/gts4 axles at the front? They would easily cope with that power level. BTW.....sounds like quite the project!
