Updating the Dash Warning Lights

There are two warning lights wired into the Webcon loom: one for the RPM warning (shift light) and another for the ECU (warns of Throttle Position Sensor error or coolant overheat).  I'd always wanted to put these on the dash where I could see them.  Only problem is both are just plain red lights, and I didn't want to stick labels on the dash.  In the end I came up with a solution: 3mm Letraset and spray enamel.


The best method seemed to be to apply the letters to the warning light and then to add one quite thick coat of enamel.  Just enough so that it did not drip.  I tried two coats on another light and the second coat melted the first and it looked a mess.  Also I found that the Letraset had to be rubbed very well onto the light or the enamel would lift the areas of Letraset not properly in contact with the warning light surface.

Here is the end result, all four key warning lights right in my field of vision, or peripheral vision if I am looking at the road.


The dash doesn't look this scratched in real life.  Its the camera flash that seems to be very unflattering.



The alternator warning light was the original from Tiger.  I didn't have this fitted originally as I was planning to use the low voltage warning on the Acewell digital dash, but I hadn't realised that the alternator will not charge the battery unless the warning light is in the circuit.

The oil pressure light was added to replace the one on the Acewell.  I was not happy with the Acewell one as it was fairly small and partially hidden behind the indicator stalk.  I wanted this important warning light right where I could see it.  Only problem was they are only available in yellow.  Any production car has them in red, and so they should be as this is a warning as opposed to a caution.  My solution was to get a blank red warning light and add the word 'OIL' myself.

Oil Pressure, ...Finally

Finally got an oil pressure reading, but it did cost me an oil filter...

Tonight's mission was to check the oil pressure:

Battery connected - check
Starter motor wiring okay - check.
Drive belt clear of obstructions - check.
Oil filled(!) - check
Spark plugs removed - check
Oil pressure gauge temporarily tee-ed in to oil pressure switch - check

Time to turn the key.  Click, whirrr.  All good.  More whirrring, no oil pressure.  Scratching of head.  Key turned again.  Click, whirrr.  Still no oil pressure.   Hmmmm.

Had a quick search on Locostbuilders.  Seems to be a not uncommon problem.  One solution is to prime the pump and the oil filter.  Tried this by pumping some oil down the oil filter threaded spindle.  Also half filled the oil filter.  Tried cranking again.  Still no joy.

Frustration building.  Then thought, let's just prime the pump via the oil filter inlet and crank over, with no oil filter fitted.  At this point past caring if the garage walls get sprayed with oil.

Tried cranking again.  Success!  Maybe it worked better when there was no back pressure on the pump?  Anyway, refitted the oil filter and cranked for longer.  Oil pressure built up steadily to around 40 to 50 PSI.  Job done.


Next job is to find a replacement oil filter.  In my haste I trashed the casing of the old one with my cheap chain  type oil filter wrench.
