Mazda temperature gauge

[widdowson2008]

Never having seen a Mason modified temperature gauge in operation, I have no idea where it settles down when up to temperature.
Is this somewhere near the truth?

Standard Mazda temperature gauge

yes to both steve,but it does depend on the motor conditon.
the 1oo ohm mod on haydns site does somewhere inbetween the 2 pics.

So there are 3 variations? Are these about right?

the 100 ohm mod sits a little lower on mine. but generally they seem ok to me.

[widdowson2008]

Thanks Ady.
From what I understand, you are saying that GENERALLY they are correct but may vary slightly from one Bongo to another, EXCEPT for the standard Mazda gauge which will be the same on any Bongo. (does that make sense?)
Just trying to get a few facts together.

yes

Also bring into the Mason mod factor that the more electrical load (headlights/ heater fan on full) the gauge can go a little higher!!

Mine has for four years... & still freaks Bellhill! I like this though Steve, calming to look at... Unlike my own gauge.

Hi Jaylee
Ultimate idea is to put some true temperatures against the dials (part of this fact sheet I'm doing)

[widdowson2008]

...........Like this

The scale shows what is actually happening in the coolant in the head, even though the gauge needle suggests otherwise.

Ohhhhhhhhhhh the advantages of REAL TIME numbers.

Sorry - got bored and fancied doing summat

I have to admit some kind of digital read out engine temp is still on my to do list, but your fact sheet would clarify..
The diagrams & findings you have put up so far have been a great help understanding what's happening!

Just seen the last diagram!!

.................digital read out engine temp............
Been monitoring mine this way for the last 2 years. Being a numbers freak and someone who likes to know EXACTLY what's going on, I fitted it from day one. Sensor point changed in November so it accurately reads coolant temperature at the head, and it now is absolutely priceless (for me).
It shows me that the thermostat is healthy and doing exactly what it is supposed to be doing.
There is a cheaper way to do this than the one I have got (TM-2), again supplied by Haydn.

Hi Jaylee
So.....are you saying that the Mason modified gauge shows not only a temperature change in the head, but will vary according to the electrical load of headlights/ heater fan on full, etc?
Does this happen on all Mason modified gauges?

I wonder if cockpit ergonomicists would say that assimilating data from a digital readout requires more pilot attention than noting a needle position.

You might be interested in the new "Temp Gauge" factsheet that I've just posted in the members area. Thanks to Ben for supplying this. See http://www.igmaynard.co.uk/bongo/news.htm

Excellent Ben - That data is just the sort of info I'm looking for.

Very true Mike. However, the difference is the EXACTLY the same as reading 2 books - one fact, the other fiction (In the case of the Mazda gauge, Noddy springs to mind ).
