Thanks for that Badwolf! I do like pictures!

Thanks for the response. That’s the exact fuse box I’ve ordered. The whole buss bar thing makes sense now… I think! The photo shows what I’ve got and I think it’s pretty standard. Looks like I’ll be developing my soldering skills as my electrical understanding! Thanks again for your help!

Hello again. I hope you are all fighting fit! So I’ve decided to bite the bullet and upgrade my fusebox for my Spitfire 1500 after the usual list of electrical maladies! I’ve read an article shared with me on how this can be done (cheers dougbgt6) and I’ve ordered the appropriate fusebox. My question is about bussbars (apparently!) Sadly I’m a visual learner - for me pictures are the way forward - so I need some stuff I’ve read clarifying. Let’s take the wiring into my top fuse. I have three green wires on one side leading to 1 white wire on the other. If I’m going to put the three green onto separate fuses I need to make that 1 white wire have three connections. What’s the best way of doing that? Bussbars (busbars/buzz bars) are mentioned. Is that just a copper strip across the three white side connectors? If so, how do I do that? Is there a better/easier way? Please be gentle. I am a bear of little brain. If you have pictures/drawings even better! Cheers Jonathan

I know I want to! I'm just not sure I have the ability!

With my test light and multimeter in hand I started probing and found that there was no power getting to the switch! Nothing across the middle fuse… that’s a problem I’ll deal with later….. so I’ve plumbed it into a different power wire and hey presto the horn is working. So now I can go and get it MOTd and then have a look at the wiring on a rainy day! The fuse box seems a little tired…. is changing it or upgrading it a big job?

Thanks for the guidance. Unfortunately I'm working at the weekend so can't make the show.

Cheers Matthew. Ignition off but also the same with ignition on. The horn works when wired directly to the battery (scared the hell out of my 2 year old daughter!) Electrics are a dark art to me. Learning as quick as I can though!

Hi guys. Finally had some more time to try and resolve this horn issue. So I popped my multimeter into the purple slot on the block as per DanMi's instruction and what I got is shown on the video clip. I don't think that's right somehow! 20210809_141005.mp4

Just ran a wire from purple black to purple and...... nothing happened!

Quick update. The horn works when current run across it. Now to check the wiring by doing the trick DanMi has suggested! If there's a loud band heard over the Midlands you'll know I got it wrong!!! 😉

Thanks for the suggestions. I’ll go through your check lists over the next couple of days and then get back to you! If there is a relay where will I find it?

Hi there people. I hope you are all well. My pageant blue W reg spitfire that you so graciously helped get back on the road last summer is coming up for its MOT. The problem is I’ve lost my horn! It was intermittent for a while (due to a loose wire) and now it has totally gone. I ordered and have fitted a new indicator stalk supplied by Rimmers which does everything else but still no horn. I then looked at the wiring and there appears to a missing wire in the connecting block of the new switch. A purple one! What can I do? Is there an alternative way of wiring the horn to say a push button on the dash or a centre push on a steering wheel. Your advice as always will be gratefully received! Cheers Jonathan

Thanks for the help (again) I found one of the bolts on the flange was very loose! Tightened and hey presto no leak! That also helped the running. So all good! Time to get out and enjoy the open air!

Hi there guys! I hope you are all well! So, after last years amazing success at getting my 1981 spitfire back on the road (with major help from this forum) I find I must once more call upon your knowledge! Shortly after passing it's MOT the old girl decided to blow her back box (at this point can I clarify that I am talking about the spitfire and not he wife!?!). Anyhow it was happily bodged with tape to keep me going until a new part could be sourced and fitted! That was August last year..... I fitted the new back box today! Never one to rush into a job. All fitted and fastened and I started her up only to notice that there now appears to be a blow around the seal for the manifold to exhaust. As there appears to be no damage other than a mighty draft coming out of the join would I be right in thinking I should just be able to undo the bolts, clean up the surfaces and pop a new seal in? Next up, she doesn't seem to be running to well. I'd love to learn how to set up and balance the carbs but I don't know where to start. I've watched all the Youtube clips and I get the theory, I'm just not confident I've got the practical skills. Is there any one local to Rugby who does mobile tuning/balancing? That's all for now..... I'm sure there'll be more to follow! Cheers again Jonathan
