Pulsing lights

[Tony_TVR]

Hi,

Got a problem with the Chim, it has pulsing head and dash lights.

I think this is down to a bad earth somewhere. I have whipped the rad out and done cleaned up the one at the front.

Reading the bible there are 3 more (wing, and two on the centre console. Can someone please tell me how to get to these and if they have any other ideas.

Cheers,
Tony.

Did you disconnect the battery, if so, make sure the terminals are spotless the put them back on, you can then smear them with Vaseline or grease.

Havnt had the battery out although certainly something for me to try.

Cheers,
Tony

Also check around the alternator connections as the pulsing has to be the output of the alternator, let us know if you get the fault cured, it's always good to have positive info on TVRs.

Check your 100 :spit: amp fuse and the connections to the alternator whilst your at it

If they all look good get your alt tested at the local auto-electrical place.

I agree with the alternator output for the pulse but funny everything else is fine inc. charging.

I will keep you informed.

Dave, considering the amount of trouble the 100A fuse causes, would there be any downside to removing that fuse and replacing it with a direct connection?

Stick it where your coilpacks are Fester. Remove the starter - alt link completely & reroute 2 nice big brown wires along the lines of the engine loom to the fusebox/battery, would be my advice.

Theres nothing wrong with fuse per se, just the location & exposure (manifold heat + road st). I also prefer the midifuses to the strip fuses, as well as better made holders

If its any use my alternator output was fine with the voltmeter but fluctuating wildly on the scope(i had the flickering lamps also)sometimes a voltmeter can not see rapid fluctuations even digital ones,i decided the voltage reg was AWOL after checking earths/feeds the obvious etc,a new alternator cured the fault,i could of just renewed the reg but the old unit was high mileage and could not be arsed,hope this helps.

I had this problem and it was the 100amp fuse next to the starter under the car the little cap had poped open and the fuse got dirty, gave it a clean and the problem solved

Check the simple things first it is easy to spend £121 and it could turn out to be a 20p fuse

Put a scope on the alternator and it and the rectification is breaking down with the heat of the engine.
