Any neat solutions, pictures, of a MK3 with an extra oil pressure warning light?

This unit converts the charge warning light to combined charge and oil pressure warning.

no of course not but when you are riding and the warning light comes on you will at least be aware of a problem

Not likely, but as with old triumphs, it may call for the oil pump to be serviced. My old bonnie's OP light used to flicker at idle (and most BSA's), upgrading to a Morgo oil pump cured that, and even with lighter oil on a hot day the pressure is good. Light should go on when ignition key turned, should go off when engine fires. Simple as that. If you've crossed your oil lines (not uncommon), this will tell you VERY quickly. I think that as long as one understands the basic limitations of an OP switch, it will do its job... with much less complication than a gauge.

Apologies in advance for the simple(ton) question

What do you connect the switch to, I presume you need to supply a warning light & mount it somewhere?

Add me to the list, always wanted something to indicate oil pressure like I have on my Triumph but didn't like the extra plumbing required for the dial gauge solution, this is an elegant, simple solution, add me to the list :mrgreen:

That's one of the drawbacks to this solution, I suppose. Because Norton's never came with OP switches (unlike triumphs and beezers), you will either have to sacrifice one of your existing lights (hi beam?) or find someplace else to mount a small light. For my part, with no turn signals I just used that bulb. It's a simple one wire hookup.

Thanks for the info., that's a really interesting and clever product.

Very useful indeed.
Also, If one attempts to start his bike with this warning indicator and can't recall what the different flashing means...
Then it probably means one has had a few too many, and shouldn't be riding his bike home.

Got the switch from Don, took about 20 minutes to install. Switch works as intended - key on, warning light goes on. When the bike fired, warning light went off. No flickering at idle, though the bike wasn't completely warmed up (too cold to ride here), and my pump was serviced recently. But all in all, simple and cheap peace of mind IMO.

Kit as sent by Don, looks like a standard automotive OP switch which can easily be found. Will make replacement simple. Titanium double banjo bolt, two dowdy washers and a female spade terminal included.


Simple 1 wire hookup (ground wire), I used the turn signal light in my headlamp (not running signals), but you could use any of the others, or find a way to mount another if you don't want to give up one of your headlamp bulbs. Since I ran out of lucas bullets I had to improvise. In my case, the female side of a standard auto store bullet connector (with the plastic sheath removed) is a perfect snug fit in the lucas bullet connector terminals.


Banjo with switch attached at the timing case, I oriented mine down at about 45 degrees ensuring that the rocker oil line ran below the switch (as per Don's advice).

There is free space at top of the Mk3 console if you are prepared to sacrifice the "ignition on" letters.

around 3-4 weeks before available, just waiting for my lot of switches to arrive from the US,

Hi Don,

I got in touch with the chap who does the clever dooda L.A.B. mentioned above. He said it would work as long as "The oil switch you fit has to work like the ones on eg T140s ie low pressure it makes contact to earth +ve, high pressure it goes open circuit."

Can you confirm that the oil pressure switch you supply work as per the description above?


Kevin

thats correct

Don,

Thanks for the confirmation.

Would this switch work with one of the mini LED lights that are available? I like the idea of the switch, but I am using all of my original idiot lights. I would think adding a mini LED to the headlight shell would be the simplest solution for me. Thanks, Josh

All the switch does is open/close the ground circuit, so assuming your LED is a two wire (+/-) hookup it shouldn't matter

Update on the oil pressure switch for the warning light, they are done and ready to ship. Come as previously pictured . You will have to supply a length of wire to go from the switch to your warning light in your headlight. I may only ship these once or twice a week by Post Office airmail as its 1-1/2 hour round trip to the Post office, shipping by courier is out of the question as it will cost about $28-$30 to ship by courier.
$30 +$6 shipping if interested.

What is the pressure setting of these switches? My Triumph and a BSA I once had came stock with these switches and if I recall correctly they were set to 4 lbs pressure.

I think 4-5 Lb is pretty close to the mark, I think thats pretty much standard on most auto oil pressure switches.
I think if it was 15-20lb then you would probably not be game to ride your bike.

Really? 15-20lb is much closer to the point you should start worrying about your oil pressure. If the pressure has dropped to a permanent 4-5lb something is definitely wrong way before you got informed by your warning light. My point is that an oil pressure switch doesn't say much (just that there is 4-5lb oil pressure and hopefully more!) so if you want usefull oil pressure information the only right thing to do is fit an oil pressure gauge :!:

exactly, fit an oil pressure gauge if you wish, the pressure switch is only to tell you that you have pressure, What does the oil pressure switch (light) tell you in your car? that you got pressure, thats all.

And where in rev range should you have those numbers? Seems that the general consensus within the many "OP gauge reading" threads is that 5-10lbs at idle is normal on a warmed up bike. As Don noted, the idiot is just that, a simple and uncomplicated way to tell you that you have no pressure...
