Vixen S2 handbrake switch arrangement

[anonymous-user]

Having found there is no handbrake switch or any signs of it, does anyone have photos or a spec of what should be fitted? I know it is some form of sprung arrangement I presume on a bracket on the chassis but thats about it!.

Many thanks Andy. The spring appears to pull on the switch is that correct? Strange arrangement!

Having looked at this and the Vixen wiring diagram I cant see how the system works. I know I'm thick but the two switches are wired simply in series so the brake fail switch must always be on for the handbrake switch to operate so thats OK for a) handbrake on b) handbrake off - but c) handbrake off and brake failure = no power to the bulb??

I simplified the description, but in series as per wiring diagram the brake fail must always be conducting for the handbrake switch to work.
Handbrake on or off the switch works the earth to the bulb. When driving the handbrake switch is off so if brake fail cant earth the bulb.

Am i missing something?

That would explain it. I was using this diagram and it can't work unless the handbrake switch is earthed direct as well, and switches between chassis earth and battery earth, so when it's on the latter the PDWA switch can come into action. Which also means they are the wrong way round on the drawing the handbrake needs to be the one nearest the warning light

Just looked at the proper wiring diagram - the correct arrangement is as I thought. Bloody internet diagram is way out! There's so much incorrect info out there....

Yes, if when you look up 'Vixen wiring diagram' the most well drawn and plausible result is wrong you do have to wonder. Thing is that some of these things become a yardstick and then people use them as future reference.

A lot of people use the John Upham list for parts but it desperately needs correcting and updating with the combined current knowledge.
