False alarm Bad soldering caused a constant 4.15v on the output This is doing my head in! Not much left to replace

I looked back on the posts and found pin one and now have replaced the optical coupler…… the output voltage is now 0.1v higher than the input regardless of temperature!!!!!!! So I will fit it back in and take some pictures….. Watch this space

More parts arrived Replace tc4s58f, no difference I have a tl4941 to fit, I can see pin 1 on the new one but which is pin one on the board? Is it to the corner if the board or down beside the lower of the transformer? Thanks again

I have managed to clean them all and the only two components not showing any details are the two 3 pin devices?

I’m just trying to get it off now with some alcohol and not having much luck in identifying the 3 pin devices.

I think that they have used that size for stability. We know that it’s only working at low voltage and current so I’m going to try it, not much to loose is there!

Hi Kenny I just tried the link and its ok? how odd My board is back in for a moment, ill take it back out over the next couple of days as I have some more bits arriving and the second hand unit maybe here by then. I will look when I get it back out, what is the best thing to use to clean the...

Hi Eddy, I unsoldered the board from the motherboard and then refitted it the first time. I am thinking of using some male and female pcb pins like these...

I'm sorry to trouble you again Kenny, that sounds a good idea and I will try it, can you pin point which resistor is the 100k please? Will this still give me the same symptom though, if I set it with the correct resistor in its place, what happens when the board is 70 degrees inside the mcu...

Quick reply Kenny, Good news anyway found a second hand one out of an accident damage vehicle to I would like to think its ok! Hopefully it will arrive in a couple of days. The plan is to clone the new one and then check the voltages on the hybrid board before putting the board in the vehicle...

Just a little more advice needed Is a 2015 inverter the same or a superseded part of the 2012 one I am working on at all?

Morning and thanks Kenny. Here is my shopping list set to arrive tomorrow: Standard Items Ordered Reference: 163596551 AD8677ARZ Analog Devices, Op Amp, 600kHz, 8-Pin SOIC Stock no.:709-7326 Qty:3 Toshiba TC4S584F,LF(T Schmitt Trigger Inverter, 5-Pin SSOP Stock no.:144-5204 Qty:30 I just wish...

Good news and bad news..... I started it and stopped it loads of times today and it has gone into ready every time. Drove her around and done ten miles, have to say it drove really good. After coming back it didn't start.... P1A15 is back. I checked the live data, battery voltage 353v...

Is MC74HC the correct item for the 5 pin component?

We do need a spare board and I would prefer a proper fix. I would love to get a new board made and then just fit the components but dont know how to go about it. The most important thing from my point of view is that I now have a working car and this proves that the fault is with the hybrid...

UPDATE Thanks for getting back to me I got fed up!!!!!!!!!!! so....... Got the decade box out and connected it as someone had previously shown, In the end a 1.5m ohm resistor performed best throughout the voltage ranges so I fitted one and tested it over a period of a few hours and varied the...

I also have now replaced MC74HC or what we thought as that and my output dropped to 3.2v, I have now refitted the old one and we are back to 3.8!!!!!!!!!!!!!!!!!

Has anyone tested a known working board? Is the input voltage on VH VL meant to appear on pin 3 and - exactly?

Update Replaced TL4066 Replaced TL4941 Replaced capacitor and resistor above +12 pin Replaced capacitors above pin 3 return voltage Still the same!!!!! Any help appreciated

Good afternoon, Now i'm in need of some help, Replaced TC4066 and when measuring had only 3.5v on the output, replaced it with another and now 3.775, so perhaps this is not the fault but I am aggravating it! In turn its AGGRAVATING me! What should I replace next? To top it off when heating...
