Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

That is a really trashed pair of resistors, and the little one exploded! Those parts are on the AC Input side. i would want to check all the parts on the top board in the AC input circuit also, e.g. lightning arrestor and fuses, plus the AC relay and EMI filter coils and cap. i would suggest to repl...

Re: Warning Codes - Car with ! Exclamation Mark

Yes the 12V aux is a critical item required for driving and charging. Hopefully that is your only issue, and typically it is only a temporary fault. Let us know how it works out for you.

Re: DTC P1A29 Motor over current

Howdy Mark, In my case it would cause complete shutdown and throw the HV error light (car with !). Replacing the aux got it working again. The car was later under a recall of the MCU; i was getting the P1A15 failure for the HV capacitor to reach voltage within time limit. i'm working on a car right ...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

The component that you have circled is actually a resistor on my board, and is marked "331", which measures 330 Ohms. The IC304 is marked "277 147", which i think is an Op Amp such as the OPA277 from TI. i don't see any vendor marks on the chip. IC301 and IC311 are also this same...

Re: DTC P1A29 Motor over current

Howdy Mark, i had this happen years ago before i had the scantools available to read DTCs. And before i understood how critical a good strong 12V aux battery was for proper operation without nuisance issues and problems. Do you have a voltmeter? If so measure the open circuit voltage of the aux with...

Re: Quirky Remote Charge Timer

Yes that is helpful, i had assumed that the timer was stored and would just use those settings without the need to activate the remote every time the EVVSE was plugged in.

But now i know--the rest of the story. Good Day!

Quirky Remote Charge Timer

i've read the manual numerous times and searched and read all the posts on this forum, but for the life of me couldn't understand how to make this thang do what i wanted, which is to not charge to FULL all the time. It was not clear to me, but the Delay and OFF Timers get turned OFF every time you d...

Re: Trouble with gearbox, un-drivable at the moment

Are you having some really cold weather in your location? The gears are always meshed, so if it rolled with little effort while in Neutral, then i think that rules out a mechanical issue with the gearbox. The motion of the shifter lever moves a sliding electrical contact, actually 2 sets of sliding ...

Re: Charging two i-Mievs

If you are trying to use the same outlet, first check the electrical panel to determine which breaker controls that outlet and determine if there are any other outlets on that circuit. Then determine if it is a 15-Amp or 20-Amp breaker? lf 20, and there are no other outlets or possible loads on that...

Re: additional electric heater

Using 2L of water and a 1kW heating element, it would take about 6 minutes just to heat the water by 50 degrees C. Then you look at the heat loss due to recirculation thru the heater core and the desired volume of air to be heated. The interior volume is 2.4 m3 or 2400 L, so there is about 3 kg of a...
