these are all very simple problems oil pressure switches just earth themselves when there is no pressure. so use a relay if the oil pressure drops it will activate the relay and cut the engine as for an altenator light use a push to make switch so that you check it when ever you press the switch no need for it to be on anyway

l agree on the face of it simple problems, l wasent worried about the oil pressure dropping more that once the float level had cut the power to the fuel pump and the engine stopped the oil light would be shining away flattening the battery, but the easy answer is dont have an oil pressure light,
alternator is more tricky as l dont think an alternator will work with out the warning light connected ?? which is why l ended up looking at the 12v time clock £7 and the job is sorted ?

hello excossack
did you used to have a lada niva by the way ?
and yes if l left it running to long it would drain the fish pond as its fed by a 2" pipe under little pressure and l with drawing out through a 90mm pipe under a lot more pressure, l do plan to dig a big sump on the end of the fish pond this spring to help matters though
red diesel will do for me, l shouldent be using it that often if l can find the leak in the duck pond
did a bit more to day, thought l might get it running but not quite as l got distracted by a new toy
will be a bit of a a squeeze on the back of my SJ though, might need an extra leaf or 2 in the rear springs ?

You'll just have to knock up something to mount it on, probably 6-wheel drive with hydraulic motors on each wheel driven by a Rolls Royce Merlin engine?

You don't want to be running it dry.... need a flow switch or pump pressure switch.
We used to fit a flow switch right at the end of the inlet pipework. Basically a microswich with a big flap, just screws into a bsp socket. And a pressure switch if my memory serves me correctly, drilled and tapped into the pump casing.
They were connected into a Murphy control panel. I imagine a flow switch could be added simply....to the fuel solenoid probably. Just need an over ride for getting it going.

you have the 6 wheel drive bit right, no hyd motors but a perkins V8 though
for testing the engine l can just select neutral on the gearbox of course, but you are right about a pressure switch being a good idea, if the suction hose got blocked or sprung a leak above water then it would stop pumping pretty quick and the pump would be wrecked, l was thinking about an oil pressure switch of an engine but just looked on ebay and there is loads of sorts of pressure switches like this one

h'mm they are very nice, but one of them switches is 1.5 times the cost of the whole pump
nice switch though

i wouldnt bother trying to use an oil pressure switch there not designed for water and will just rust / seize up
