dpb Posted March 31 Report Share Posted March 31 (edited) Hello, Persevering with the wiring and i find 2 inline fuses. One for an electric fan, which had a 35A fitted - seems a lot. And one for a fuel pump with no fuses in the holder. Any thoughts on appropriate sizes? Cheers Dave Edited March 31 by dpb Quote Link to post Share on other sites
RobH Posted March 31 Report Share Posted March 31 Some fan motors can take a very large current when they start up Dave, though I would have expected 20A to be sufficient to allow for that. (Of course it might be that a 35A fuse was found necessary by a previous owner.) A fuel pump doesn't usually take much current so a 7.5A fuse should probably be fine, but you could check on the type of pump to see what the draw actually is. Both 'continuous carry' ratings.

dpb Posted March 31 Author Report Share Posted March 31 Thanks Rob. I'll have an experiment i think, using your suggested ratings. I could really do with fitting an extra fuse box and maybe a relays holder as well - there must be such a thing. Cheers Dave I Quote Link to post Share on other sites
ianc Posted March 31 Report Share Posted March 31 Dave - have a look at Revington's site for fuse box(es) and relays. ian Cornish Quote Link to post Share on other sites
BlueTR3A-5EKT Posted March 31 Report Share Posted March 31 Durite make relays with a fuse holder included for under a tenner. I use them in my headlamp relay circuit. https://www.12voltplanet.co.uk/standard-mini-make-break-relay-normally-open-no-contacts-12v-20a-with-fuse.html Problem I hit was that I now need to carry another spare part. viz. the blade type fuse.

harlequin Posted March 31 Report Share Posted March 31 I was looking at one of these https://www.racetorations.co.uk/product/hidden-fuse-relay-box-tr2-3a/ to tidy up some of the electrics under the bonnet George Quote Link to post Share on other sites

I think it will make a professional looking job of the electrics, the only reason I haven't already fitted one is I am considering simplifying thing by doing away with the headlight relays and fitting LED bulbs.

dpb Posted April 1 Author Report Share Posted April 1 Thanks everyone. I'll have a good look at those things. Cheers Dave Quote Link to post Share on other sites
Ralph Whitaker Posted April 1 Report Share Posted April 1 I must admit my fuse box is getting a little crowded and I could do with either a bigger box, or an additional one to share the load. Ralph Quote Link to post Share on other sites
RobH Posted April 1 Report Share Posted April 1 (edited) This was my home-made solution which fits in place of the original box: ff f Edited April 1 by RobH Quote Link to post Share on other sites
Ralph Whitaker Posted April 1 Report Share Posted April 1 I was thinking of one of these FL7 4 fuse boxes as commonly used on cars of the 70s, should fit where the existing box is and gives 2 extra fuses so I can divide the loads up a bit. Ralph Quote Link to post Share on other sites
