Auxiliary Water Pump Can Destroy CCU or Even Car?

[mbboy]

Hey guys,



The auxiliary water pump on my 81 380sl hasn't been working, so I just picked one up on Ebay. However, I learned from several threads on these pumps that, if the pump seizes and draws too much current, it could destroy the CCU or even the car, as it did in this thread:

So, I'm hesitant to install it without first putting a 1 amp fuse on the power wire out.


Can anybody tell me if that problem affected the 81 380sl and, if so, is it caused by particular pumps, the car's circuitry, or both.

Thanks very much in advance.
