Temp gauge trouble shooting

[Calum]

It's a thermistor.

Read about it.

@calum do the thermistors generals go bad? They seem like gold dust

[Calum]

@declan Thermistor: an electrical resistor whose resistance is greatly reduced by heating, used for measurement and control.

I presume that's how the DTR does it.

Yes they will eventually fail like most things. It's the cheapest place to start looking.

Simple to test, measure it's resistance cold, heat it up, measure it's resistance hot.

@calum I'll look into it thank you Calum

[Mightyman]

If it hasn't worked since you first got the bike, you may have the wrong one installed. There are two different types.

[declan]

@mightyman looks pretty old guy said that it was working but he was a compulsive liar so I highly doubt it

[declan]

@declan the needle moves in the clocks when the key is turned so I know that works

[declan]

@mightyman do any of you lads recommend any other systems like universal temp gauges

[Jens Eskildsen]

I have an universal temp gauge on my radiator, wrosk good.
Goes on pretty hard, but fits both my Dt and my wr250r

How hot is the bike running?

Might be a daft question but is it getting hot enough to show on the gauge. I seem to remember my previous DT-R's would run just under halfway on the gauge.

[Calum]

@nottsbiker If the themostat has been removed, then it's going to take a VERY long time to warm up.

Very bad for engines running without a thermostat.

@jens-eskildsen thank you for that I'm going to get one as one it looks cool and mine rises but its never ever above 1/8-1/4 on the gauge might be the thermostat is not reading right anymore but it could be fine so thanks

[Nottsbiker]

Sorry only skim read

Yes is going to take for ever to get up to operating temperatures with no stat

[Jens Eskildsen]

Sounds right with the reading, mine is just above where the line in the display starts to thicken, but will get hot in deep sand or slow technical trails.

Photo for clarification, mine is usually well below this reading:

@jens-eskildsen mine don't get that far even when I been off road but I am running pure water doubt it could make that much difference but we will see as I'm getting one anyway they look good

[declan]

@terry-tz mine doesent read at all and my bike warms up real quick faster than my 4 stroke it gets really hot but just seems that it's the way the engine likes it tbh since I don't cruise any where it's always full throttle If the roads clear

[terry.tz]

@declan ye same and I'm not sure I think it moves a tiny bit il take a photo and just look like a d!ck later and keep at in the band everywhere I go I can imagine the looks now when I'm at traffic lights with my purple helmet

[declan]

@terry-tz

[declan]

@jens-eskildsen does yours sit on 20 when cold why does it do this they all seem to?

[terry.tz]

???? I'm confused at what your asking him
