Fan thermo switch

My latest 2500 project has an electric fan fitted in front of the radiator but it looks like the thermo switch gave up the ghost a long time ago - the fan is simply hard wired into a switch that floats around under the dashboard somewhere. The fan works fine so I'm going to replace the thermo switch...

Re: HS6 reassembly - choke/fast idle cam

Problem solved - there is a spacer in the mechanism which looks like it has been deformed slightly by a previous attempt to tighten this bolt (pretty sure I didn't put enough pressure on it to do this but I guess I might have done :oops: ) I swapped out the spacer from my 'reference' carb and all is...

HS6 reassembly - choke/fast idle cam

Does anyone have any advice on how much to tighten the choke cam mechanism when rebuilding a set of SU HS6s (the bolt head circled in the attached picture)? https://i.imgur.com/OcAMkPml.jpg When rebuilding my HS6s I have found that if I do this up to anything more than finger tight the whole cam mec...

Mix & match carb parts?

I'm currently rebuilding a pair of HS6s for my 2500S. I have a second set of HS6s which have the later HIF-style twin track ball roller bearing dashpot/piston arrangement which I understood was designed to reduce friction in the piston/damper rod assembly and eliminate the possibility of the piston ...

Anti-siphon valve?

Would a 1977 2500S fuel tank have an anti-siphon valve factory-fitted? I'm thinking a fuel transfer pump might be the cleanest and safest way of draining the 10+ year old fuel from my tank into a jerry can but don't want to buy one only to find I can't use it...

Re: 2500 S Project

Ah, cheers for the compliment on the blog :) I enjoy writing about the work I've done, even if not many people read it. I think sometimes when you undertake a project gradually it's easy to loose sight of how far you've actually come - looking back over a blog or photos etc can really help put thing...

Re: Ballast resistor wire

Cheers Alec,

Just to confirm - the starter feed is not required in addition to the switched feed from the ignition circuit? Is the ignition circuit live when cranking in that case?

Re: Ballast resistor wire

I've done a bit of reading up on this and it seems that possibly the easiest fix is to do away with the ballasted system altogether and fit a 12v coil. My understanding is that the ballasted system was introduced to make cold starting easier - but seeing as I live in a relatively warm climate hopefu...

Re: Ballast resistor wire

Cheers Alec, the wire is part of the main loom so is wrapped in black tape behind the dash - resleeving wouldn't be an easy option. That leaves me with either keeping the same setup with a new wire or changing the setup as per your message. My worry about keeping the existing setup is that this wire...
