    Speedometer Repair

    So I have repaired a lot of speedo's over the years. It is quite a chronic issue as our loved Supra's are getting old and tired. So the capacitors start to go bad and cause it to barely move and stay under like 40mph. So just need to go buy 2ea 22uf 50V and 1ea 6.8uf 50v. Be cautious of polarity. Long leg of the capacitor is the positive. The Cap has a silver stripe donating that is the negative leg (shorter). Do yourself a favor and buy a small $8 spool of de-solder wick, like Gootwik to suck up the solder for easy removing of the old Caps.

    https://www.amazon.com/Goot-CP-3515-.../dp/B00TCZSMSQ


    EDIT: Some may have noticed that the Caps removed are 25v not 50v. It really doesn't matter which one you get. You may find that the lowest rating is 35v for the 6.8uf. Filtering the search to just "Automotive Purposes" really restricts the availability. "General Purpose" are way more abundant. Just get the cheapest ones close to these as these are like pennies.

    One of our OG 1A1 contacted me on FB as his is showing speedo death. He asked If I could repair but I said save the money and hassle and just fix it yourself. Anyways, someone within this FB post said I should post here and make it a Sticky! So If a moderator sees this, maybe this can be stick'd?

    Hello Stu Hagen,
    I just replay new sensor speed odometer on the transmission of my 95 Supra TT 6 speed but the odometer & two trip meters is busted and the mileage odometer is not moving. This is discontinued the odometer & two trip meter so do you have any new or old one sell to me. Please let me know ASAP...Thank you Stu
    Best regards,
    Michael T Nguyen

    You probably need to check the solder joints in the odometer. Sometimes they come loose.

    I would do as said above first to eliminate the cold solder issue. There are many links to this if you search. If not then the other option is going to "bitshtr" The odds of the ODO just going bad is slim. It also could be an issue with the pink wire feed not making to to the ODO unit. Some bypass this.

    Also I don’t know about repair this speedometer situation by cold solder. I replaced new sensor speedometer but not sensor speedometer issue. The pictures of my mileage is light up and it not moving. My mechanic said the odometer & two trip meters is the problem (burn out). It’s low mileage and it would be repaired. Stu said option go to “bitshtr” and I don’t understand. Please explain please...Thank you Stu & Superaforum. Best regards, Michael
