8 Ball

Post by scimjim » Tue Apr 03, 2018 9:32 pm

A little side project for 8 ball has been going on over the past few weeks - a replacement for the 2 rod inhibit/reverse switch.

The normal constraints apply - overdrive mustn’t be able to be engaged in first or reverse and reverse lights must work (new MOT requirement).

New requirements are - overdrive must be able to be engaged in second gear, must be engaged by a “momentary” switch (not like the original “latching” switch) and most importantly, must disengage as soon as you change gear.

Firstly then, we need some micro switches to ascertain where the selector levers are. Phil decided that we wouldn’t use a single switch to determine lever position but we’d have positive switching. That means twice as many switches :D

So, some CAD:

Now to decide if relays/DPDT will suffice, or start playing with ardueno :D

That looks like a fantastic idea, i used to hate doing the flat in 3rd OD go straight 4th gearchange... being able to keep more then a finger and thumb on the steering wheel seems like a good idea 8)

Gives us a 7 speed gearbox too :mrgreen:

Could come in handy chasing down a Merc SLC 4.5 driven by a local with no idea of the word “fear”...

How about going magnetic switches? Got to be more reliable than with all that crud being thrown about. You could use some simple logic using gates or diodes, but with the price of Arduino boards, there is little contest.

only tested on post 2009 vehicles - but 8Ball will be MOT exempt anyway :D

I left the box of seat bits at home today, so didn’t get them finished, so I fired up 8 Ball and got it outside in the daylight.

Greased everything, checked axle and gearbox oils, cleaned it, swapped a tyre onto a different wheel and balanced all 4 wheels. Also played around with the rear bumper - they all need to come off again because I’m not happy with the GRP bumpers, the fronts don’t line up and the rear is a bit too wide.

Checked all of the lights and brakes etc, Taxed and MOTd it online last night (I will probably take it in for an MOT later in the year), fitted the seats today and drove it home tonight. Has a slight misfire, the digital temp gauge is a bit erratic, the fuel gauge wasn’t working (but seems fine now :roll: )

Definitely an electrical problem somewhere though, when the fan comes on the digital voltmeter drops from 13+ to 11 ish and the Engine struggles - either the fan, wiring or alternator? I’ll get the AVO out tomorrow.

Misfire sorted - another FIA kill switch causing problems :twisted:

Fuel gauge is still erratic and if I get time I’ll refit the original temp and volt meters as the digital ones are pants :D

Roundels will have to go back on Steve - they took some paint off when I removed them :D

Bumpers will possibly get carbon wrapped?

I still need the chrome door trims/seals (at the base of the window).
