Can't find it might just run without alternator warning light if I can't find it soon lolIt usually has 0v printed on the plastic housing mate.

Its not just the light, its the excite wire too, without it your alternator wont charge.
Can anyone help please? I need to know which pin on my alternator to wire my alternator warning light to? The dash says it wants to know 0v when its not charging so any of those metal studs okay?
Thanks
Yes Kenny it's the cup alternator, unfortunately the braided hose won't really shift so can't get access to the connector. Thanks for the offer mate My dash says to activate the warning light it want's to see 0V so I was hoping the 3 metal studs around the alternator would show 12v when running and obviously 0v when not but I guess i'm out of luckIf it's a Cup alternator, it uses one of the two pins in the small rectangular (might be square) plug, which can just be seen behind that braided hose on the left of the picture.
I've got the plug cut out of my old loom so I know what pin to use but it's at the workshop, I'm at home, can check first thing in the morning if it's of any use?
The FF alternators just have the main output terminal 8mm stud, and a 5 or 6mm stud so they're easy to wire up.
On a 2 wire alternator, like the Cups have, the charge light needs to be a lamp, not an LED, if your using an LED you'll need to put a resistor in parrallel with it so there is sufficient current flow for the exciter circuit. I've used a 10w 33ohm aluminium clad type, which will result in about 4-5watts at 12v, most warning lights arent anymore than 5w
Yes its probably 1mm away and -10 so is pretty rigid Thanks Kenny!Not quite sure how it manages to charge without the warning light connected up, I guess once it's spinning fast enough it must manage to get it's self going.
Is that hose really that close to the alternator you couldnt get a wee plug in there? I'll be at the workshop soon, will dig it out anyway and let you know.
That explains why it worked last year then without thanks Dan.these alternators don't need an exciter like earlier ones (williams etc). The charge light output it literally that, just an output to turn a light off.
If you look at a standard loom, one of the wires on the plug is blanked.

Do you know if the 3 metal studs see 12v when alt is running or earths?

Engine loom finished other than it needs the bulkhead connector putting on the end
Car is pretty much finished now, few odd's and ends to finish tomorrow and then next week when I have a few more days off I will take it down to Freds, connectors on and mapped and then good to go!
Thanks Dan Still might be dragging it with me to the Ring can't decideLooks very tidy James!
Thanks Kenny! I didn't use Raychem in the end looked at it fairly extensively but just chose thinwall pvc wire in the end, for what i'm doing it should be fine (I hope )Looking good, what type of wire have you used, Raychem 44 or 55 ?
TDF did my original engine loom in DR25 and it just seem to remain a little more flexible and also shrinks down in a uniform shape. The motorsport electronics guy who's doing the connectors for me uses tyco for all his stuff so i'm sure you'll be fineWhy do you wish you'd used different heatshrink?
DR25 is the mainstay of Motorsport looms but its very expensive and probably overkill for most applications.
I've been using a tyco heatshrink (not sure who owns who but they're linked with Raychem anyway) can't recall the part number off hand but its pretty reasonably priced and it's good quality. I tested some of in a tub of petrol, left it for 2 days and its still ok so I'm sure it'll cope fine with the odd splash of fuel, oil etc.
I want to but not sure I can be bothered with all that towing lolBring it to the ring James, you know you want too
warning light on a race car - if it comes on, you've already lost the race, therefore a bit pointless no?
same as guages then?warning light on a race car - if it comes on, you've already lost the race, therefore a bit pointless no?
Just got home and greeted by my new calipers thanks to Jetstream Motorsport (the people who make the Alcon kit for the clios) for the speedy delivery
Your ears when you hear something go bang?Gauges, what gauges.
Could be although the old engine loom was just laid in the same way I have done this one but I suppose the Raychem wire TDF used could of also added to the flexibility. Will be good to see what you do Getting rid of the stock loom was definitely the way to go.The difference in flexibility could also be down to how the loom is built, ideally all the cores want to be laid in concentricly twisted layers, each one in the opposite direction from the previous. If your a professional loom builder then this will be second nature but for your average Joe, quite tricky and time consuming.
I've done small sections like this before but I dont think I'll attempt it for all the looms i've got to do for this car.
I have another plan which should result in a flexible loom, be fluid proof and be easier to assemble.
I'll wait and see what it turns out like before I disclose anymore
Pointless for it helping to finish a race but if it saves other damage that costs money then no I didn't bother with the alternator warning light thoughwarning light on a race car - if it comes on, you've already lost the race, therefore a bit pointless no?
Thanks hopefully they are as good as the ones I had last year as they were very good!these look epic
Sorry Mike not had chance to do an update for ages on here I'll try and do one tonight or tomorrow night before I go awayUpdate pics please.
I've not raced my Clio, but when I'm in the zone on a trackday and driving quickly I would be too busy to look at a dash!
Looking forward to seeing the next update!
You'd be surprised, I waved to Dan and his mate, as I picked them out at Combe going into Camp corner lol.
