Simple low oil pressure blinking warning light

[dom14]

Hey guys,

A guy came up with a simple circuit to achieve above goal on below link.

I thought it's a good thing post here for everybody's reference.

I have just bought a flashing LED to indicate the anti theft system is activated. It has a maximum working voltage of 10 volts. It will operate on a lot less, so the value of resistors used can be raised so the current flow is reduced substantially.
There are plates available to fit under the oil filter that have tapped holes to fit extra sensors and switches.

Yep not a bad idea as such but IMHO if you want to mod in another telltale you are better off with an Audio alert.

If you want a flashing LED to simply put across the existing lamp circuit they are about 30 cents each http://www.ebay.com.au/itm/10-PCS-10...0AAOSwVupTpsYt

If you want an audio alert and flashing LED then $2 http://www.ebay.com.au/itm/1pc-12V-2...sAAOSwc1FXai2e

Thanx mate.
The second one is damn good. No need for extra wiring or circuitry.
Using the existing warning lamp circuit to wire up simple flashing LEDs is obviously a very good way to go about warning alarms.
It should work on both oil pressure & overheating.

Yeah, I installed a one of those sandwich plates last year for installing an aftermarket oil pressure gauge.
Then I spent hours fixing the existing oil pressure gauge sender unit(remember? ). In reality it could've been fixed in an hour with
the right tools. .
I didn't end up installing an aftermarket pressure gauge kit, but I will be installing a one soon anyway.
I wanted to install it the other day, but i couldn't find it among stash of stuff.
Easy to buy things and put them away, but not so when it comes to find them.
I'm contemplating on maintaining a database.

Sandwich plate seems to be good. No leaks, by the looks of it.

It also came handy when I did the oil pressure test with the tester.
Sandwich plate has spare plugged threaded holes, that comes handy with the test, otherwise
I would've had to undo the oil pressure sender again.

How easy was the plate to install?. I am still toying with the idea of a pre-lube canister because my Patrol can sit for days or weeks, and the plate might be an easy, cheap way of attaching it.

It's too easy. All the bits and pieces to adapt the plate for many cars are already in the kit.
I had to buy an extra plug from Pirtek, 'cos it only came with one(they obviously forgot to add two).
Two threaded holes for fitting any sensors/senders mean two plugs are needed in case we don't use it for oil pressure sensing kit
installation straightaway.

Sorry mate, I have to get back to you on the prelube thing. I'm having a bit of brainfog atm and don't remember all of it's function.
I'll do some reading and get back to you to continue the conversation on that.

Yeah, sandwich plate is apparently a better approach than using a T-joint on the sender unit hole.

I'm thinking the above diagram doesn't have all the parts of the prelube system in it.
I'm thinking a prelube pump is an obvious part of the prelubing thing, yet i can't see a one in the diagram.
I'm also thinking that pump may be the most important & perhaps the highest costing part of the system.

Do you have your own prelube blueprint already in hand with an idea of what parts to get and where to get them?

Or are you thinking about not doing a DIY prelube kit, but buying a kit off fleabay?

I think the prelube kit is more important for newer engine than an older one, but I'm sure it can extend the life of an old engine as well.

It uses the engine oil pump to pressurise the tank. The solenoid shuts the tank off as the engine shuts down, thus retaining oil at pressure. When the ignition is on the solenoid lets the oil fill the galleries.

Ok, cool I got it.
Not too hard to put together a DIY for lot less.
