Now the alternator wont keep the light on the dash out, I need A list of things to check, possibly a way to fool the alt into trying to charge the batt, like when you ground the field on a G.M. product!!! this would tell me right away weather my alt/ or /regulator is bad! in the meanwhile ive got some parts you may be able to identafie??theres a small module with cooling fins with a couple of brown #10 wires going to it with a part #a0185459932esg400below that the #84steme5001.001 hkr. another module is black with the #002 542 20 19. it has a battery symbol on it as well another mod has a 1 2 3 with lettering next to each numeral1-as 2-k1.31 3-k1.15 if any of thease devices seem somewhat famillier drop me a line as this will help me solve whats going on under this hood Tnx in Advance!!!

The 1998 model SLK is a very unusual MB, as they installed a charging system cut-off relay that was designed to work when the SRS air bag went off. The part number 002-542-20-19 is that relay & they will fail. List is $59.
