which one is the starter relay?

Hello everyone. I've exhausted my own resources so now make a plea for help. I have a 2001 galaxy mk2 1.9 tdi 115 cv I've looked for hours on the net and even went to the local Ford dealers but I havent been able to find out a part number for the starter relay on my galaxy.

The story:
 After a couple of hesitant starts the car wouldnt crank at all. Fortunately I was on a hill and it roll started no problem. When I got home I discovered that the negative lead was loose, so I tightened it and put the charger on overnight. No joy the next day. So I looked at the fuses and the 30a position 26 i think was blown and i put in another and that blew too. I jumped from the fuse holder of the blown fuse directly to the starter solenoid and the car started with the key, so the ignition switch and starter were working, and next was the relay. So following the excellent tutorial on this forum I removed the fuse box and accessed the relay holders. The problem is what I found does not correspond to what is in the Haynes manual nor any of the images I have found on the internet, including the one on the abovementioned post I used to get to the relays. I looked on the 7zap website but cant interprete the information, nor could the people at the Ford dealer so I dont feel so bad about that.
I tested the relay located on level 3 marked 103 with code vw 357 911 253 (52/00) and it works, coil closes and circuit activated. The wiring going in is red, while the wiring on the starter circuit (to the solenoid) is red/black. So I tested the relay on level 2, which has red/black wiring, and is marked 185 part number vw 3b0 911 251 (50/00). The marking on the side of the relay were different than what I found inside. The outside says 85/86 (coil) and 30/87 (circuit) but the base was marked 2/4/6/8, and the coil activates with the 2/4 which are adjacent rather than the 2/8 or 4/6 which are opposite as the 85/86 and 30/87. The coil worked and closed the contact, but the circuit was not completed, at least the multimeter didnt beep.
So my next step will be to jump the relays with a wire with two spade ends and a fuse in the middle in case I get the wrong connections. I certainly dont want to fry the ignition switch or some other component, so I thought I'd ask here to see if someone could give me a part number for the starter relay and I could check that first. There are only 6 relays that could be the one I am looking for, so how hard could it be? From what I understand if it were the famous 109 the car wouldnt run or there would be at least some things that didnt work and everything is as before except for the starter circuit.
the question: Is there a specific relay for the starter? If so, anyone have the part number?

Sorry for such a long post. Hopefully it will be understandable. I have a Seat Alhambra same year and supposely the same car but I have found out that many of the parts though VW are not the same nor interchangable, so I dont think it's worth taking the fuse and relay assembly apart on that one, especially as it is the only working vehicle I have.

Hmm, tricky... could you get down to the breakers yard and get yourself a whole handful of those relays and switch the whole lot over?
I drive a Seat Alhambra 1.9Tdi which has 115bhp and an automatic gearbox.

I am happy to help you with all your questions. I am not a qualified mechanic but seem to be better at fixing my car than even the most experienced garages.

I have lots of friends here and very much enjoy talking with you all. Always remember, a motor car is a serious tool and should be treated with respect. Put your safety first, always.

Hi. Rather than replacing my 20 year old electronics with other 20 year old electronics I think I would rather buy a new lot. There are only 6, and they seem to be going for 5 to 10 euros each. I have mucked about a bit more and if I remove the number 185 the 30a fuse for the starter circuit doesnt blow. The coil tests ok, but I'm not sure the throughput is working. When I stick in a fused wire to complete what I think is the circuit to the starter soleniod nothing happens. Neither fuse blows, nor does the starter click or turn over. The problem is I dont really know what the relay number is because as I said in my post the case and the wiring schematic on the outside doesnt correspond to the pin numbers on the bottom or to what actually activiates the coil.
