I still need to load the latest FW. I think mine is a pre-production unit as I was in early testing, but I do have some valid input here already. In using both the HK3-C and supplied ciggie-plug PS's I get rebooting problems. My old van does drop charging at idle, but I have done testing while holding engine speed well onto where it charges as indicated by ammeter and lighting brightness, so in those conditions low or dropped voltage will not exist. So if it is a powering problem, then it is due to the supplied PS and HWK malfunctioning.
In occurrences it seems to be temperature-related. When cold (0c or 32f) the cam usually reboots around 5 times before it stops trying. Sometimes it just keeps trying till it works. No pattern to this. When the cam ceases trying a 7-second press of the power button is needed to get it going. Again it might try several times and stop, or try until successful.
Once the cam stops the initial rebooting it sometimes keeps working, sometimes reboots a few minutes later, or sometimes shuts down with the beep until I again do a 7-second press of the power button. This will occur with engine at road speed so the alternator is charging constantly. Again the colder the cam, the more likely this will happen. Once the cam warms up several minutes it usually functions correctly, even if I stop and turn the van off a few minutes or half-hour. Rarely in these times when I start driving again the cam will not start without a 7-second press of the power button. Also the cam keeps going once well-started even if I'm idling a few minutes at a red light and charging is minimal.
At the end of the workday when it is warmer the cam usually behaves better, but still sometimes boot-loops a few times before it holds. I have reset to default settings and reset the cam multiple times using 2 older FW versions and still have this problem. In the summer on the earliest FW or two I had no problems like this regularly happening. The A139 next to the T130 is flawless and even when I switch PS sources from ciggie-plug to HWK.
It seems to me that the problem is likely going to be found in the supercaps resisting charging or needing too much current to charge, or in the charging regulation circuit for them. The effect either way would be to no longer have enough energy available to keep the cam going until the supercaps are completely charged. Yet it normally takes mere seconds for supercaps to charge while the re-booting lasts a few minutes, so that doesn't make sense either.
Readers please remember mine is a pre-production cam which may be different then what is being sold today!
