HELLO OVE! It's been a long time....nice to see your name pop up again.
Nice work on the fuse panel. Glad to see you're still at it. |

Thanks for the information
Ove,
Thank you for the response. I have a 71T that I have assembled the majority of parts for a fuse panel upgrade similar to your original project. Your latest one, if you don't mind, will be plagiarized for the early car for many reasons. I think it will fit my early much better in the left battery box. Happy New Year.

Souk,
Good to hear from you too! I've been busy lately, but I finally got the time to find the pictures of the installation and post them here. Dan, Good to hear that you find it useful for your own car  Send me a PM if you need any help (tech info or finding parts). Pål, I'll PM you soon. Happy New Year to you all

I relocated the battery to the smuggler's compartment. This completes the electrical modifications. At least for now.
The old battery was 17 kg. The new one is 9.5 with the mounting plate and brackets. We'll see if 30A is enough...

where did you get the relay holders? I have been looking for that type for a while just had to order one from porsche and it didnt have the metal connectors in it when it came.

Ken,
The relay holders are from "Biltema" a local auto parts store. They were around $ 2 each. Send me a PM if you want me to get some of them for you. I would prefer to have the stock round relays, but those relay sockets are $ 51 each (!) from Pelican. Add $ 21 for each round relay and you can see why I used the regular square ones instead. I could have bought used round relays and sockets, but judging from the poor condition of my old ones I decided to buy new parts.

Did you add flyback diodes to your relays?

Info for anyone interested...
Flyback: "One other consideration when using relays is the current spike created by the coil. When a coil of wire has current running through it, a magnetic field is created. This closes the contacts of the relay. When the current is removed from the coil, the magnetic field collapses and this causes current to flow through the wire until the magnetic field is completely collapsed or gone. This can cause a damaging voltage spike back towards the logic circuit. This is called flyback and is avoided in the above circuit with a flyback diode." From: http://www.acroname.com/robotics/info/articles/drivers/drivers.html Example:

Uhhhh... neither the headlight filaments nor the manual switch contains any active devices. I suppose a switch could qualify as a logic circuit since it has 2 states...

I believe a flyback diode is built into the standard fuel pump relay, that's why I asked.
And the explaination above, while correct in it's theory, is not correct for this application.

I'd still cover the "hot" side of the battery terminal with some kind of rubberized protection..... - Wil

I spent way to much and had one shipped from porsche in germany. But thanks for offering.
