MRT PT's do not work in the cold!

[Dudders]

Numerous issues today with MRT PT's not working in the cold! Had to warm the cars up in race control in order for the PT's to count.

Looks like a few of us are heading over the 'Harrys' (not Purcy) PT this week.

Mount them on you motor and save millions!!

One assumes that they've used commercial (0-70deg) chips instead of industrial (-40/+85 deg) however that's got to be marginal. What temp was it trackside Dudders? Were the lights on the PT or was it just not working?

[Dudders]

Instead of solid blue light they were flashing blue. Heated up for a couple of mins and they were solid and counting. Some didn't work at the start of a race but did when the cells/motors warmed!

Odd.

Interesting, it appears that the unit knows there is a problem. I'll take mine apart this week if I get chance and do some thermal testing at work!

I would guess that the voltage regulator is the problem....

Been using MRT's for about 5 years in 8th Nitro in very cold conditions, never had any issues, are these a new batch of MRT's?
