surfup* Posted February 23, 2014 Share Posted February 23, 2014 Hi All, Has anyone got or know where I can get a volt stabaliser for the rear of the clocks. The gauge on mine is reading low, and the alternator is running fine. I do appreciate the assistance. Best regards TP Link to comment Share on other sites More sharing options...

stradacab Posted February 23, 2014 Share Posted February 23, 2014 What he said! We do this every 6 months and the semi is the only way to go. Can we get this one pinned in the relevant section please? Link to comment Share on other sites More sharing options...

spiney_norman Posted February 23, 2014 Share Posted February 23, 2014 If your voltage meter's reading low that's got nothing to do with the regulator on the dash, that only affects the petrol and temp gauges. Link to comment Share on other sites More sharing options...
surfup* Posted February 28, 2014 Author Share Posted February 28, 2014 Thanks for all the advice, I have bought a regulator, but if it is not the regulator what could it be? Any advice? Thanks guys Link to comment Share on other sites More sharing options...
spiney_norman Posted February 28, 2014 Share Posted February 28, 2014 I'd start with checking and cleaning up any earths, but then again if it was my car and I knew the alternator was charging fine then I wouldn't worry about the gauge Link to comment Share on other sites More sharing options...
mantadoc Posted March 2, 2014 Share Posted March 2, 2014 Norman is correct the voltmeter is the dash is not regulated by the voltage regulator. Chances are the voltage regulator is faulty as they often are HOWEVER, LISTEN TO NORMAN this is not your issue. Link to comment Share on other sites More sharing options...
plumster Posted March 3, 2014 Share Posted March 3, 2014 Mmmm, will fitting one of those things stop my temp guage going to the "dark side" on the right? Link to comment Share on other sites More sharing options...
spiney_norman Posted March 3, 2014 Share Posted March 3, 2014 Probably, it'll also stop your fuel gauge from over-reading! Link to comment Share on other sites More sharing options...
mantadoc Posted March 3, 2014 Share Posted March 3, 2014 No warranty of any kind implied or given and no liability for any loss, damage or injury, no matter how incurred accepted. Old case and stripped board, and a few gubbins from your friendly mail order electronics folks. As I intended this to be adjustable it uses more hardware than some of the various designs I have seen on the net <BR> Going to be a tight fit. Prototype, no finesse and blue tack used as a third hand.<BR> This tested out ok on the car so it was time to do better. Thought about where stuff was going this time (note pot position).<BR> Left wires long to mount IC externally. IC is bolted to the case, note that this ICs mounting tag is internally connected to the pin2 output. Without the insulators the outside case of the regulator could be at about 10 volts. Note the 3 wires coming out of the grommit on the right so they can be connected to the IC pins and of course the grommit so it doesn't chaff. There is also a grommit in the top by the IC. Finished item. IC pins are heat shrink sleeved. I am ashamed to say I wrapped some electrical insulation tape over the bolt JIC. I would have preffered to heat shrink sleeve that too but didn't order any in that size. With an Ohmeter I checked all pins for continuity to the case to make sure there wasn't any, and from the IC to the case too. In situ. The usual mod of running a small loom is in place to save having the cowl off all the time. Screwdriver through what was the top grommit to adjust. Picture of the board and components as I wired it. The wires to the IC pins were diff lengths so I knew which was which as they were all black. Note the Dip in the Electrolytic capacitor for polarity. Potentiometer has 3 pins, 2 are on either end of the "track" and the other is the adjustable bit. If you use the two nearest together you don't get any adjustment Link to comment Share on other sites More sharing options...
Julian Posted September 14, 2014 Share Posted September 14, 2014 Only just seen this, WOW! wish I had gone to the same school as you, my knowledge of electronics is "switch on or off" or "plug or unplug" !!!!! Link to comment Share on other sites More sharing options...
mantadoc Posted September 14, 2014 Share Posted September 14, 2014 Only just seen this, WOW! wish I had gone to the same school as you, my knowledge of electronics is "switch on or off" or "plug or unplug" !!!!! I've forgotten most of what I ever learnt about analogue electronics, what remains is how to follow a circuit diagram and solder. Transistor theory has gone. However, the above has been floating around on here since probably 2005 or before. Basically it is a circuit diagram that I found on the net just built tidily into the case, where possible, I think the diagram was in a recent magazine, however, I prefer mine.
