Choke light
First time here. Looks like a great site. Just bought our first vette, a 1980 yellow L48. We love it. My question is, the choke light is on. What is the exact cause of this. I traced the wire from the choke back to the wiring harness on left fender. Don't have a wiring diagram. Does this feed from the alternator, or is it a sensor turning on the light. Any help would be appreciated.

Re: Choke light (Bodiemountain)
Hi & welcome (good place to be),
Normal reason for the light being on is a blown choke heater fuse (20A?). Does the choke work (are you getting voltage at it?). The wire from the choke goes to the choke heater relay, which is fed from the fuse. From memory, this relay also connects to the generator. My choke light was staying on, mainly because the choke was permanently on :eek: It turned out to be a bad connector to the p.circuit behind the clock cluster (may have been the gage cluster which was also bad).
Hope this helps a bit.
:cheers:

Re: Choke light (Bodiemountain)
Is the light on solid or just slightly and varies with engine speed? I have an 80 and if you have a blown diode in the alternator this will be the effect. Also causes a slight hum from the relay. The alternator is still putting out a charge but its now a half wave instead of a full wave rectifier. LOL Jamie

Re: Choke light (UKPaul)
Thanks for the reply. Found a description of system and brief wiring diagram on internet. Your probably right. Will check fuse and choke relay. Also will check behind clock display, since this is the only item that doesn't work on the dash. Any help as to the location of the choke relay, am assuming it's in the dash area? Thanks again.

Re: Choke light (jamiejamison)
Thanks for replying Jamie. The alternator is putting out fine. The light is on solid and bright with no variance at different speed. Believe the problem is going to be in the choke relay. Will let you know what I find. Thanks again.

Re: Choke light (Bodiemountain)
Hi,
I seem to remember that the choke relay is behind the side of the centre console on the drivers side (somewhere around the area of the drivers seat base?). Sorry I can't be more specific, but I had so many electrical bits apart at the time, its all got a bit hazy....
If you get really stuck give me a shout & I'll search it out again (I've got to pull that area apart again to fit my new carpets, so it's no problem).
