Before you do any soldering work yourself, it would be better to send the board to an expert repair service with solid soldering skills. Cosmos is the guy.
As i said, i can pay half the shipping cost.
You should drop him a message. Cosmos is available on every amiga forum including amibay :)
Okay, the goliath style psu has a 5v line from a molex. Ive tested the line with my multimeter and its providing 5.18v. It plugs into the fan connector on the BPPC red to red and black to black. 5v and gnd. Its ready here for me to flick the switch. Can someone just give me the go on this? Dont want to fry the board :PQuote:

That scares me.
I think i know a fair method for both.
Send it to an expert who donīt know both of you or a 100% trustful neutral person.
If the card have a defect like worn outs slot or something else like icīs or bad soldering ... on the card than xanxi must take it back or pay the full repair cost + shipping.
If the card have no defect than itīs wasagi problem.
But maybe you find the solution before you send it anywhere
I am not happy that my BPPC is not working, but I must take it in good faith that the card was sent as working. My only desired outcome here is a working board so I can start enjoying my amiga again.Quote:

Dont let this put you off this site, 99% of the deals here turn out great.
I just cant afford repair costs at the moment, so any tests/work/diagnostic I can do here with advice the better!
Yes i know ...
But no matter if xanxi knew it or not when the card have a defect than there is no other option.
i think my advide is absolute fair.
You tried your best but you can nothing do more to bring it to work
Okay this is how my powerboost is wired. I'm pretty sure I'm correct on this but I REALLY dont want to kill this card. The only things I have done to it so far is stroke its pins with a pin and brush it with a bit of IPA.
Testing the voltage from the PSU connector. It comes off from the 5v line on a molex.

How the fan is connected by default

How I propose to plug the 5v line to the card

Looks fine to me :thumbsup:
Just remember not to leave it on for more than a few minutes without the fan!
While waiting for a reply on my 5v wiring I reinspected the board using my loupe. There is some rework to the battery connector, but it also appears that heat has affected some of the edge connector pins. Not sure if you can see this clearly, could these be the culprit.

Thanks, just waiting on a second opinion :) 5v the wrong way is not healthy :PQuote:

No damage to main board nor the accelerator.
Giving 5v directly to board via fan connector has not helped matters. This purely seems to be a connector problem in some form. Thankfully the board still boots if I hold it in place.
Cosmos has suggested I give the edge connector on motherboard a good rub with a rubber to see if it clears the contacts. I will try this later when I have some time.
Thanks for advice :)
