CURLY Posted August 19, 2009 Share Posted August 19, 2009 as above really, i'm looking for the part number for an ignition light resistor for my 2.5 td, as i think mine has had it.. Cheers, CURLY Quote Link to comment Share on other sites More sharing options...
errol209 Posted August 19, 2009 Share Posted August 19, 2009 as above really, i'm looking for the part number for an ignition light resistor for my 2.5 td, as i think mine has had it.. Cheers, CURLY Having just found a value for it in the 200 tdi wiring diagram (1000 ohms) the maximum power this thing could ever dissipate is 0.196 of a Watt, so "2W Res 1K D1K £0.22" on this page here would do just fine, if you don't mind a minor mod to your harness to fit it - the joys of heatshrink Quote Link to comment Share on other sites More sharing options...

errol209 Posted August 20, 2009 Share Posted August 20, 2009 be interested to know where & in which wiring diagram you found that resistor value, no mention in my genuine Defender workshop manual about it on the wiring diagrams/ Sorry, it was a 300Tdi diagram, but I think my logic holds Source of diagram 300TDi 97 model year, see page 4.1., Item G101 Extract of diagram: 1E3 is written in full as 1 x 103 or 1000 Ohms. At 12V this allows a current of 12mA (0.012A). The warning light is shown as 1.2W, which at 12V gives a resistance of 172.8 Ohms. I guess from this that the resistor value is a compromise between providing sufficient excitation current when the bulb has blown vs. the bulb only coming on dimly (because of the parallel resistor).

CURLY Posted August 21, 2009 Author Share Posted August 21, 2009 No worries, one more regular question sorted! was it a regular question then? i did a search, but can never find what i'm looking for! many thanks for your help you guys, i bought a prc 9096 one in the end, and with a bit of jiggery pokery managed to make it work in my butchered loom!

Cheers, CURLY About three or four times in the last month or so, I think, but this is the first time we've managed to work the value of it in ohms! Ah, the search facility - some patience required there, but no worse than Goggle. Happy to help (that's why some of us are here, that and trying to beat Mr Western to a reply now and again ).
