ok im in the belly of the beast I am going to do my best to describe what I am seeing as I have no idea what I'm looking at ( well kinda at best) at the top of the box full of wires there are a bank of little boxes two rows of three the top left is blue green in color is that the starter relay ???? thanking you in advance ,scott
Based on above message, I guess I have to assume you do NOT have a BMW or CLYMER shop-manual... otherwise you would find a lot of what you need, including photos, in chapter 9 (CLYMER) or section 61-General electrical equipment (BMW shop manual).
BEFORE you start with these checks / tests, make sure the battery main wires are disconnected (Black / ground will be enough).
Under fuel-tank, the electrical-relays junction-box is in 2 sections: UPPER section is all relays and lower section is mainly a lot of connectors from various components.
See 3 attached photos to follow me:
1) If you have the "old-type" BLACK starter relay that is present mainly on 1998-2000 models, then this will make testing easier as you can disconnect one of the LARGE wires and test for continutiy (OHMs selection of a multimeter) across both large poles. If continuity is present, then the relay can be assumed to be fused / stuck. You can open and clean/sand contacts, but you are on borrowed time - in most cases, this could happen again.
2) If you have the "NEW-type" BLUE starter relay that is present mainly on 2001-2009 models, then the harness/wiring is a bit more complex, but you can pull the relay from it socket for testing. These have an internal "smart-circuit sensing for low voltage" to avoid starting with low battery. Hence, it is NOT probable this newer type would be welded / stuck.
The old-type BLACK relay is NOT available anymore from BMW parts catalog, so to replace or fix an old-type BLACK relay, you have 4 options:
A) Buy the expensive BMW retrofit Kit to install the newer type BLUE relay (you need to be comfortable with wiring to do so). See item 1 in link below from MAX-BMW parts catalog:
MAX BMW Motorcycles - BMW Parts & Technical Diagrams - K1200LT 99-04 (89V3)
B) find a used old-type BLACK relay on EBAY hoping it will be better than yours (a long shot with unknown electrical part)
C) substitute a universal car starter relay available at any auto parts. These 2 round large poles arrangement are common design. For the 2 smaller wires (activating the relay coil) you may to do some wiring connector job as the type of connectors will vary in automotive world.
D) Clean the old relay contacts, but add an additional car starter-relay under the seat to minimize load / wear on your old relay. There are a few threads here on forum on HOW-TO do this:
