Can anyone please identify these relays for me?
"F" - I understand is the fuel pump relay.
When the fuel pump goes on the blink, which terminal do you jump to get the fuel pump working?

Car is a RHD 300 SEL with airconditioner.

I just went through this whole thing last Friday-check back in this forum'Fuel pump relay-location?'

To answer your specific question quickly-jump sockets 7 and 8.

cheers

As an aside you should Really get those aluminum fuses out. Dis-similar metals[xx(] only lead to issues.

Jonathan’s right, I replaced the fuses with the brass/copper alloys in all my MBs. Cheap insurance. That fixed the ACC problem in my 123.

Reviewed your earlier thread. The markings on your fuel pump relay don't seem to match with the # you quoted. Reading the marking on the relay pins
Left --> Right, First Top --> Bottom:-
Top row :- 31;15;87;87H
Bottom Row :- 50;TD;30;87k;67V;TF

Which holes corresponding to the above pins are to be jumped ???

Apart from the fuel pump relay, my interest was to identify the other relays in the photograph A-->G
Can anyone please help?

Jonathan :- Thanks for the tip - must get around to change the fuses to copper.

jdc1244a :- I been wanting to ask you how & what to do to get one of those Temperature Gauges shown on your reply to my queery. If I get one, it will display the Temperatures in Singapore for all to see.

That's why i referred to socket numbers and not pins on the relay.You have to get your head in with a torch(flashlight) and check the numbers on the socket into which the relay plugs.They are numbered 1 thru 12.

As mentioned in my topic,the handbook makes no mention of relays and i too would be interested to know the function of all the others.I'm pretty sure that info will be on the maintenance CD,if anyone would be kind enough to post.
