Help please Fuse popping

[Deanofire]

so your saying replace the large black relay and the 4 little blue relay's but dont replace the latching fuse just test it ?
could there not be an intermittant fault with the latching relay ?

 

[V8Druid]

where would i get the skinny blue relays from ?
are these them

looks like the same pin arrangement as the blue one and has a diode

the black relay is the latching relay BTLs

the blues, if the same as the one in the pic, are as per your link above

need to see the pins on this one

and this one

and this looks to be conventional SPDT (single pole, double throw)

There is another version that looks exactly the same as this too.
It's SPST (single pole, single throw), but with two common output terminals (S6 & S8 below)
You can tell them apart as the SPST type has two (87) output pins
the SPDT type has output pins 87 & 87a

Are we talking 87 and 87a? Or two actual 87s!

 

[Shovelhands]

Two 87’s , clearly shown in the diagrams above. Can’t say I’ve ever seen one or knew one existed! I can’t really see the point in it, must be such a specialist item? And just because there’s a drawing of it doesn’t mean you could get one from anywhere!
