Strange Speedo problem...

Re: As for the Brake Light Switch

It's only when you get into deep sh1t that the wife and/or screwdriver would benefit from some superglue. You just have to apply it in the correct place in the right quantity, but don't leave it lying around for others to use, there might be repurcussions.
If you have a spare switch, you must plan on replacing it sometime in the future. It's not recommended to plan to replace your wife. I did the calculations, and it's not that practical or economical.

I got the new Switch

Re: As for the Brake Light Switch

If you find diving down the foot well difficult you could install a hydraulic switch into the system in the engine bay. But obviously needs extra plumbing work.

Re: As for the Brake Light Switch

I would caution against making access panels in the bulkhead. In some old editions of Pitstop there is talk of bulkheads cracking and a Marlin supplied reinforcement bracket.
This seems to be more prevalent in non servo cars, where brake pedal pressure may be a bit higher, but it's certainly closely related to the pedal pedal box area.

Re: As for the Brake Light Switch

Well done....

on my head, feet in the air

If ever I get around to rebuilding a/the Marlin I'm going to make several removable access panels in the bulkhead so I don't have to do this any more. At least the builder of my car had the forethought to put one in the bulkhead in front of the steering column so should I need to it maybe easier to get at related items. However getting at anything mounted centrally, like instruments, is a nightmare and that's with my dash mounted flush with the rear of the scuttle moulding. I don't know how you guys with dashboards mounted further forward manage to get at anything.

Re: As for the Brake Light Switch

In case of future repairs, on some hard to reach things, I often change the fixing screws to studs loctited into the hole.
Quite simple then to slide something like this switch onto the stud and then spin a nut on. In the top of my socket drawer is a blob of Bluetak, ready to temporarily locate a nut into a socket, that won't then fall out, another tip is to superglue a washer onto the nut, avoiding even more fiddling, particularly useful when handling small non magnetic parts. I have even been seen super glueing stainless screws to my screwdrivers.

This works particularly well for things like a Marina mechanical fuel pump, that has two gaskets and a spacer, and sometimes a heat shield that are conventionally bolted together. Not so easy when you are trying to work against the pump spring as well.

Re: As for the Brake Light Switch

Exactly the item I suffered with.. trying to get the two bolts into the housing unit after fixing the inside of the switch was hell. Had to keep a stick jammed onto the pedal so the housing could be positioned right over the holes which you can not see. I used a small allen key to align one hole then put a nut into an 11mm socket and the bolt in on top - so that the bolt would be held 'shallow'. This helped tremendously to hold the bolt upright as I could grip the socket easier than the tiny threaded bolt... I don't envy anyone that gets this problem...!

As for the Brake Light Switch

Resolved the brake lights - it was the pedal switch; internal component was corroded and out of sequence with the inside spring, removed, disassembled, cleaned, reassembled and refitted, sounds easy but I did most of it on my head, feet in the air up over the seat. Everything works. Mot booked for tomorrow...

I was out for a spin the other day and the bloke behind me at a set of lights pipped his horn and shouted to me saying your brake lights don't work.Cheers mate I replied,then thinking oh bugger,wonder what that is ??.Got home and as you say head first into the cockpit and at 68 can only manage to get half way in !! lol..after checking the 3 fuses under there and looking for loose wires which thankfully I did not find any and the fuses o-k I'm thinking where the hell is the brake light switch ??.So went under the bonnet looking for one and no luck .Back into the cockpit and spotted the switch with a powerful torch shining into the abyss where yer feet go.There it was at the back of the top of brake pedal assembly fitted into a bracket that was held down by 2 bolts.The switch actually screws into the bracket making it adjustable in or out to get the plunger in the right position to operate the switch.There is a cotter pin that goes through the bracket just under the switch as well so it stops the switch moving about when in place which makes it impossible to adjust when in position.You probably all know about this info but I had not got a clue until this happened so perhaps this info may help someone in the future.So try and keep Fit,Slim and very flexible and very bendy in case you too have to sort out yer brake light switch on a Marlin Roadster.Mine Marina based.P.S. still aching 4 days later and arranged to have my arms lengthened by 6 inches so I can reach under there better !! if I ever need to again.HOPE NOT !

Re: Strange Speedo problem...

Passed mot with ease However this 35 mile round trip has exposed a few other issues, rear shoes sound like they're intermittently binding with the drums & the carb is maybe running a bit too lean... stuff to do tomorrow...

Chances are you have the premier wiring systems loom - I am hunting out the schematic for it later today and if I find it I will post it on here for you
