Plasma Dial wiring

[the janner vanner]

I have aquired a set of plasma dials, but the wireing has been cut, so, could someone please help me by looking at the back of the blue/green switch which has 6 terminals, and the rocker switch which has 3 on the bottom twist control.
I have a block "Epicenter E12-9080" with 3 cables coming from it, 1. cable to the dials; 2. red and black = live and earth; 3. The cable which has been cut with 9 wires staring me in the face not knowing which goes where.
Thanks
Dave

Hi Dave - It's hard to tell because of the heatshrink, but this is what I've got on the Blue/Green rocker switch:

Orange Blue White
Yellow Black Green

Orange and Yellow are on the "1" side of the switch; White and green on the "0" side of the switch. Hope this make sense and is unambiguous.

I'm afraid the heatshrink is too far down to see the wires on the rotary switch.

I'll try to post a pic in a miniute

Front and back pics, so that you can line it all up:

Back:



I *think* that I have coloured the rotary switch correctly.

Been thinking of getting some of these myself because the dash lights are fairly dismal are they easy to fit into the siting look and are they as bright as they look?

They are pretty easy to fit. Just be careful not to overtighten the screws on the temp gauge dial. I have a Mason alarm, and damaged the temp gauge coil when I reassembled. I was able to repair it with a soldering iron and some help from the forum though. As long as you don't overtighten the screws, it really is an easy job.

The kit includes a couple of corner pieces - don't bother using these - you can't see them properly in situ anyway. Instead, follow jaylee's example and use them to make your indicator arrows white - they look really good like that.

BTW, The seller is near you - based in Swindon somewhere.

the corner sections only need the dark coloured perspex taking off ,just push them out and throw away.then the dials look as bright as the rest of the dials,

Ah - good tip, didn't think of that Still, when you put the corner pieces in, make sure they line up perfectly with the images underneath - otherwise you get blurry warning lights.

Is there a fact sheet on taking the dash board apart to fit this thing. If not then any clues?

[westonwarrior]

dismantling the dash is very stright forward and simple 4 screws and the whole thing pulls out, then unplug the connectors and simply undo the bits 1 at a time, very simple, search fo 626 speedo fitting for pictures some where on here,

i am at work on mobile so can't look for links

The dials come with full destructions of how to remove the dash/dial pod....... you will be able to clean up the dash pod "glass" up inside and out, I was shocked at how dirty my "glass" was...... easy to fit, as dvisor says don't overtighten the dial retaining screws, I tightened down so it just "nips" the dial, check the swing of the needle and if it catches just a gnats hair more..... took me 2 hours to fit (I did a mason at the same time as well as cleaning and cable tidy work)

4 screws on the dash surround. Lower your steering wheel and the stalks, then tease out the surround. You may need to squash it a little to get the top lug through. Make a note of any wires going to switches in the surround - esp. fog light. These may come off if the cables are shortish. This exposes the perspex and dial assembly, which are held in with 4 screws. Undo these, remove the dials assembly and unplug the two long white connectors at the back. These will only fit back in one way, so you don't need to note which is which. I believe some Bongos may have 3 connectors. Unscrew the Mason alarm screws on the back of the dials, if you have one fitted (and note the position of the screws).

You can now take the dials indoors to work on. The front perspex and dial surround are held in the assembly by lugs, which you can carefully pop with a flat bladed screwdriver from the back, being careful not to break the lugs. You can remove the perspex and surround separately, but I removed mine as a pair. This exposes the dials. The plasma dials can be slotted over the old ones after removing the little screws. You shouldn't remove the needles to fit them, they just slide over with minimal coaxing.

Fitting is obviously a reversal, but check everything works before fixing it all back. You'll need to find a suitable feed for the power. Mine is connected to a wire feeding one of the bulbs next to the auto select lever, so the dials only light up when the headlights are on.

Removing the top part of the steering cowl by when the steering wheels dropped helps free up a little room when releasing the pod surround & switch banks... It stops any accidental scratching of the top of the cowl too

Sounds like this is too easy even for me to stuff up. I shall have to buy one and give it a go.
Before i do though - I assume this thing plugs into the existing wiring and doesn't require me to feeds endnless miles of extra cables everywhere. Also I note that there is a switch gizmo too, will this fit into one of the blank switch areas i have on the dash surround or does it just screw on somewhere handy?

You'll need just a positive feed and an earth. Taking the feed from a bulb near the auto select is a nice easy, neat job. The switch is more of a problem - I've not found a good place for it yet that looks right. Some people have replaced the switch and rotary dial with more bongo friendly switches, others just set it to the desired colour and brightness and then hide the switch behind the dash.
