Cheers TT. Glad you haven't given up either.

Ok, it's been a while so I thought I would post an update. I haven't given up on this project and I have been back and forth with the people who designed my PCB and we've been slowly making improvements. I also got a bit of a refund from JLCPCB as they made a few mistakes too. Good news is that I've...

it could be the DOPS board itself is faulty couldn't it ? That's the bit that does the self test - you haven't incorporated the DOPS board function into your new replacement board have you I have the ribbon PCB installed again at the moment and the self test is working fine, so I think that rules o...

Perfect, cheers Robsey. That matches what I have. It looks like my wiring is good, so it could mean it's something on the board?

I may disconnect one of the pressure switches to see if it sets off the DOPS alarm next?

Tested the LED with a multimeter and it is working fine.

Apologies for not posting anything for a bit. Work and life have got in the way. I have done a couple of tests with the PCB though. Good news is that I have driven the van with the new PCB and all seems well. Bad news is that I still can't get the DOPS warning light to work or test flash on start up...

Yes, I think I have the schematic. Where should the oil pressure light connect up to?

I ran another test this evening. I checked all my wiring and reattached resistor R3 and ran it without the DOPS cables, incase that was the issue. Wiring looks spot on, but I still have no oil light on the dash? I've reached out to the people who designed it for me to see if they know what's going o...

Thanks Aidan, I will try and sort this out now. They must have changed their rules recently.

Did a quick test this morning. Van starts and all LED's are working apart from the Oil Pressure light. Oil pressure light does not even flicker on and off when ignition is on. Will need to check my wiring. I'm not getting any voltage from the alternator either, so need to check my wires on that one ...

Is that last picture not working? I uploaded it the same way as I usually do. Honestly, I haven't given a lot of thought to selling these kits (my better half has though when she found out how much I spent 😂). I'm still learning about PCB's and I still want to develop the design more. If I had a bit...

I've ordered 2 replacement GEMO speedo cables recently, and both have snapped where it connects to the back of the speedometer. 1st one lasted 3 weeks, 2nd one only lasted a week! https://i.postimg.cc/76hnYRjm/IMG-20250912-154707.jpg https://i.postimg.cc/D0bQ1XvG/IMG-20250912-154726.jpg I've made su...

Ok, I think it's finished. I've double checked the DOPS connections using the old ribbon PCB and I'm confident I have them in the correct order. Jumper caps arrived today and I think I have all the necessary one's installed. I've left the LED 6 jumpers vacant. There are a few things that need addres...

Right, I got some wiring done this evening. I had most of the right colours, but brickwerks were short 3 of them so I had to improvise. I had to order some jumper caps too, as the PCB's didn't come with them. They should be here tomorrow though and hopefully I'll be able to test this over the weeken...

I made a bit more progress this evening. I soldered in a green LED for the for the indicator and replaced the High Beam LED so it's the correct height. I left LED 6 where it was as I'm not sure I'll use it anytime soon? I removed resistor R3 as this could interfere with the DOPS system on my Dash. I...
