84 190E.... is it a eurobenz?? i was thinkin.. good news. the magnet has come down in price. if yours is an electromagnet you can change pumps and fit the slightly newer style of the magnet that does not have extended mounting reach. look them over in your part suppliers web pages. You will see what I mean. then, I find, the UK version of the haynes manual depicts the electrical circuit in a way thats easier to understand. you can request it at the public library. its called HAYNES UK mercedes benz 190, 190E, and 190D (83-93) service and repair manual by spencer drayton and steve rendle ISBN 10:1859604501 or, ISBN 13: 9781859604502 the whole accessory drive, belts, pulleys is different depending on what you are working on. I just received proof that my eurobenz has a 2.0L and all this time I thought it was a 2.3L. I was looking for 4 speed manual trans info. Dr. Sternschnuppe ran my vin and gave me the facts.(benzworld) hope this helps!!!!
