So I have been working on my s13 finally (sunshine yay), and I installed the impul speedo (0-260km/hr), however here’s the funny thing, when I turn on the car, it goes to 10km/hr (the first line) and sits there, when i turn off the car it goes to zero… sometimes it is just at zero. Twice it went up and I thought it started working… but it didn’t ☹ What could it be? My only posiitve thinking was that it could be some kind of resistor or capacitor that went out… but any ideas? It cost me quite a bundle to get… which sucks so yeah… only thing better is the nismo one 0-280km/hr but yea. Secondly my cluster clock light doesn’t work… I replaced the bulb from another cluster I had but it seems that bulb doesn’t work either, when i shake the bulb its fine the whadja ma call it in english thing inside the bulb is not broken… whats up? It doesn’t look dark/black or anything for that matter… any ideas? I’ll try another bulb again when I take it out I guess. So yeah… please help 🙂 ---

does the speedo work when you drive? you may have to reclock the needle… and for the clock, check the fuse. ---

no it doesn’t, its just stuck at 10km/hr, however it did twice move, and then it fell back down… and another time i think today i forget, it went up to 80km/hr then stopped at that, and went back down… What do you mean by reclock the needle? Oh I didn’t know the clock had a fuse… the clock itself functions, just the light of it doesn’t (and it’s very useful at night or any time for that matter to know the time while I’m driving). ---

oh, sorry i didnt realize it was the light only. it may be a loose or broken connection on the printed circuit board. try other bulbs and see what else. as far as the speedo… it may be a loose connection in the printed board or inside the unit itself. tough to say. id say double check by making sure a stock speedo works perfect… and if it does, then the impul unit might be fucked. ---

yeah the stock works, so its not the speed sensor as far as i know… the stock stopped working when i broke it (i was a retard and wanted to paint the needle redish to be more visible… bad move on my part i learned my lesson). That speedo was a jdm 180 speedo… it worked before i broke it. The USDM 180 speedo i had was broken when i bought the car… thats the history behind it all. The reason I got this new speedo was as a fix and upgrade… but … 5 months after i bought it (as my life was very busy), i found out now its not quite functioning… Well the rear of the speedo the board was slightly u could say… ‘rusty’… and there was some connection between two soldering points (just a naked wire) it was a bit rusty sort of too… I suppose that could have some reason in it… This could be very well be the cause, i suppose i should clean it with alcohol?.. i kind of cleaned the dirt myself but it didn’t change anything… I still assume it is some kind of capacitor or something gone wrong… hmm… ---
