A con'fuse'ing issue...!

[grifterkid]

Hello there folks...

This is just a quicky but what fuses do I need for my Toledo (1976, 1300 4-door)?

The ones that I have at the moment are 35a 17 amp so does that mean I need 35 amp or 17 amp?! I went to my local motor facter (I couldn't get over the fact these still exist but thank crikey they do!!!) and he told me I needed 35 amp (continuous?!) ones so that is what I purchased for the princely sum of 50p each!!!

I am an idiotic novice so please try and help me out...

[Jod Clark]

Those will do. I'm not sure what the 17/35A rating actually means....17A continuous, 35A blow perhaps?

[tinweevil]

17A continuous, 35A surge.

[grifterkid]

The fuses I have just bought have 35amp on them, nothing about 17amp... the thing that I am worried about is that the filament inside looks much, much thicker (wide and flat) than the ones already on my car (thin wire)...!

They'll be fine, trust me.

On your noggin be it sir...

All my triumphs plus my series landy all run 35amp.

Well they shouldn't!
They should be, as Jod & Tinweevil said; 17A continuous, 35A surge. Get 'em changed now before the wiring melts instead of a fuse when some smoke escapes.

Hmm, must try to do something about that.....

Since I've converted to a modern fuse box with blade fuses, should they all be as near to 17a as possible then?

Ideally no.

You should add up the maximum load on each fuse (if everything that runs off them is on) and add about 50% to avoid nuisance blows. So, say you've got your dipped beams and interior light on one fuse, that'll be 2x 55 Watt + 1x 5 Watt bulbs = 115 Watts = about 10 amps at 12v. Add 50% gives a 15A fuse for that circuit.

In practice, as long as you don't rate the fuses too much higher than what was protecting the wiring originally, you'll be fine. So that's all of them at 17A, which isn't in the standard range. S0 try 15A and, if you get any circuit regularly blowing, increase that one to 20A

I am no comedian as you may've guessed...! However, I am pleased to hold the accolade for worst topic title pun... What do I win?!

Just quickly coming back to this for some help...

I have been purchasing 35 amp fuses from Halfords and using those but they do not last long at all...!!!

One discovery I made was that I still have the factory fitted 'spare' Lucas fuses in my fuse box and they are labelled as 17 amp...!!!

From what I can tell the 17 amp one is the one that keeps things 'steady' so should I be switching to those instead?! I'm very confused as I did read somewhere that a 35 amp fuse was the one to go for but I fear I might have taken that in the wrong context...?!?!?!

What do you wonderful people think?!

If your fuse(s) keep blowing then there is a problem somewhere. You need to ascertain when the fuse is blowing.
