Greetings,

Currently I am having a few problems with a number of relays/fuses. I have searched through the web and currently can't find a replacement.
Is there any way for some help in my research.

Unless someone knows a way to actually tests the functionality of the relay using a multi-meter or something of that sort.

Man: Siemens

Relay: (Yellow) Part # 61.36 - 1389 105
Relay: (Blue) Part # 12.62 - 1735 424 (Fuel Pump Relay)
Relay: (Green) Part # 61.36 - 8353 447
Relay: (Purple) Part # 61.36 - 1388 911

---------------------------------------

Also my fuel pump isn't getting any power. I tested the white connector and it doesn't read anything. By chance could this be relay related or is there something else I can check in the mean time?

v/r

you can test the relays by checking the continuity of the circuits in the relay. Multi meters have a funtion what tells you whether or not two sources are connected. I would assume that using that you can check the relays.

^^^The function is actually called what you said: continuity. But you can't always judge a relay through that. You may get continuity, but the relay could still be defective in that it doesn't pass enough current anymore. This is particularly true of relays for O2 sensors, for example.

ebadeau: are you looking for these relays for your '93 325? Your relays must have been replaced before because the OEM brand is Bosch, not Siemens. That said, you probably won't find the Siemens part #'s referenced anywhere. But just replace them with the Bosch counterparts and you'll be fine. Pelicanparts.com should give you all the info you need.

good point sir.
