Instrument cluster LED T10 install not working, dodgy rheostat...https://www.classic-ford.org/mr2/mr2play/tm.aspx?m=103803(c) MR2 AUSTRALIA30Re: Instrument cluster LED T10 install not working, dodgy rheostat... (dennis the menace)Right on both counts - Merry Christmas!<br/>https://www.classic-ford.org/mr2/mr2play/FindPost/103860Wed, 25 Dec 2013 08:03:31 GMTRe: Instrument cluster LED T10 install not working, dodgy rheostat... (Tree)Yep had a play around a bit more and indeed they are polarity conscious. Removed the little white variable resistor now all is working fine! Seems to have unlocked the power since LEDs apparently have a threshold voltage?<br/>Such a minor mod with a big reward :)<br/>https://www.classic-ford.org/mr2/mr2play/FindPost/103858Wed, 25 Dec 2013 01:22:30 GMTRe: Instrument cluster LED T10 install not working, dodgy rheostat...

(dennis the menace)Yes, LED's are polarity conscious. &nbsp;Also you'll need to have the dimmer turned to maximum - or remove it and simply connect the two wires together.<br/>https://www.classic-ford.org/mr2/mr2play/FindPost/103813Mon, 23 Dec 2013 18:41:32 GMTRe: Instrument cluster LED T10 install not working, dodgy rheostat... (just_ace)Did you try switching the leds around? Iirc they only work one way.https://www.classic-ford.org/mr2/mr2play/FindPost/103810Mon, 23 Dec 2013 18:00:35 GMTInstrument cluster LED T10 install not working, dodgy rheostat... (Tree)Tried replacing the cluster bulbs with T10 because my cluster is really really dim, but they're not working, even with rheostat connected. The LEDs work fine as battery tested them. I have suspicions that someone back in JDM-land tampered with the rheostat, but one begs to question why?? I have a replacement rheostat which as 3 wires and (ordered from a UK eBay seller) but my "stock" one only has 2 wires. I guess they somehow combined 3 wires to 2...<br/>And the retarted thing is that my dimmer switch works counter clockwise (dimmer as you turn clockwise).<br/>So without further ado, HELP!!<br/>https://www.classic-ford.org/mr2/mr2play/FindPost/103803Mon, 23 Dec 2013 14:30:52 GMT
