Title: My lights on the C3 just stopped working now won't raise ??????
Post by: 69CVET on December 06, 2014, 05:22:35 AM: Gents.
Everything was working fine a few weeks back , now the lights won't raise at all ?
Got some tips on where to start before I get myself into a spin with the vacuum system ?????

Tried the manual switch makes no difference. All fuses are ok.
Any tips all help would be appreciated.

Thanks.

Post by: COD on December 06, 2014, 08:40:30 AM: I would suggest you visit Dr Rebuild's website and download the vacuum hose diagram. This will give you a good understanding of how the system works and then you can begin your process of elimination.

Stupid question but you do have the engine running don't you?

Yes mate Engine was running heading to the man cave now to go over it.
Check small hose on the vac relay (front of hood) for vac with bypass on. Should be able to feel/hear it with hose off. If OK all dash control is good.
Relay acts like a tap. big hose from inlet should have vac while ever engine is running. Oulet to vac motor has vac only when small line has vac on it.
Very common for one or both relays to leak enough to stop operation. If so work out which leaks least and using a couple of "Ts" operate both motors from the best relay.
Good luck!

Post by: COD on December 08, 2014, 03:39:58 PM: Hey Choptop, did you find the problem? I just re-hosed mine so I now have a better idea of how it all works. Let me know if you need a hand.

Post by: 69CVET on December 08, 2014, 09:53:14 PM: Hey COD.
Won't get another chance to look at it until Sat or Sunday.
I'm heading down to the Sunday morning doughnut and coffee at Krispy Cremes on Sunday morning at Penrith I'm hoping to get a tutorial crash course from the boys in the club then on this Vac System

I did check our your site you recommended. It requested a payment to download but a lot of info on there.

Talk soon
Chris.

Post by: 69CVET on December 14, 2014, 08:43:03 PM: Hey COD.
Thanks for the diagram today and your great troubleshooting skills to find the problem. Glad it was a simple fix. I had the 3 issues today all within 2 hours. Lol.
Hopefully our 2nd run will be less troublesome. Thanks again for your help.

Cheers Chris.
