Do you want a low coolant alarm at £22.17?

Ok peeps, now have a kit of funny shaped electronic 'bits'. When I work out how to stick them together my progress will be here when I work out how to stop the soldering iron blistering my fingers.

I, for one, look forward to hearing the results.... (I can lend you a pin if you get blisters)

Don't hold the hot bit?

Make sure you polish the tip of your iron and dip it (and the piece you are about to put it to) in flux, or you will get slag build up and it will be hard to join the components together. Wipe off any surplus material and let it cool down fully before you put it back in its holder. Once you've done that, you can get on with the soldering

Ok peeps, as usual life gets in the way of having fun but I have eventually stuck it together. There are 3 probes top one fitted at the high level. Second fitted at low level, the third goes in the base of tank.

The output wires are fitted to a buzzer from Maplins ( 2 quid and LOUD). The alarm goes off when the level drops to the low level sensor, this stops false alarms until the level is low. The alarm stops when coolant reaches the high level probe.
I did need to change two thingies to make it work but only cost 30p.

Did you measure a current draw TGP? Curious to know how it compares with other setups..............

Sounds good...have you actually fitted it to the Bongo or a test rig at this point ?

Sorry guys my puter is deciding what posts send me a response.

It is fitted Haydn.
Tested it for you Dandy, glad I did. It is 2.4 mA. The zit covered kid in Maplins gave me the wrong resistors.
With SS screws I dont think there will be a problem but will test it down to find out how low it will go.

TGP....that is a "HUGE" amount af electricky you are putting into your cooling system.
I think I have my sums right but please accept my appoliges if I have got this wrong.
2.4 mA = 24,000 micro amps.
It is no secret that our alarm is at between 25 micro amps and 45 micro amps @ 2 volts.
(our latest module is 24 micro amps)

At best you are putting into your cooling system 533 times the current and up to 960 times the current at worst.

This is not going to be good for the radiator or any other alloy parts of the engine. Should you have any brass/copper/solder then things can only get worse.

I know some peeps will say "he would say that would'nt he" There are the findings of our research for what it's worth.

Strongly advise you either disconnect it asap or get them amps down.

It will also start to break down the properties of the coolant.

Does this help?

da (deca) = x10
k (kilo) = x1000
M (Mega) = x1000000
G (Giga) = x1000000000
T (Tera) = x1000000000000

d (deci) = /10
c (cent) = /100
m (milli) = /1000
µ (micro) = /1000000
n (nano) = /1000000000
p (pico) = /1000000000000

Maybe TGP meant microamps

I don't think so......2.4 micro amps ?? We wish.

Check your maths Haydn.
2.4mA=2400 micro amps.
