MATCHING MODULES

Today was pretty eventful, as the 1998 Mercedes Benz SLK Class 2 door convertible hardtop with 0nly 34000 miles was being delivered. A half day off work was taken but really was not needed, as the car did not arrive until 7:30 pm.


MERCEDES BENZ SLK CLASS

Since I was off and just waiting for the car to be delivered, I decided to start hooking up the front battery module. The cables in the front had to be trimmed and the connectors needed to be drilled so they would go over a 3/8 in stud. Once they were drilled, the cable was prepared and they were crimped onto the cable. Heat shrink covered the connection and insulating boots were pushed over the cable. Voltage readings were taken on the front and rear modules and they were very close to the same voltage.



FRONT MODULE CONNECTION


FRONT MODULE IS 123.0 VOLTS


FRONT MODULE IS 123.1 VOLTS

Since the modules were only .1 volt apart, I took a pair of needle nose and placed the last cell connector on the battery terminals and started the bolts. When I tightened up the bolts there was a slight spark and the modules were connected. 


LAST CONNECTION MADE

Then, just to make sure both the modules were working properly, a drive was taken to the Marathon Convenience Store to pick up a 6 pack of Big Vic Imperial IPA. I felt a little celebration was in order, as this had been a busy day. The car ran fine and it will be interesting to do the first charge with both modules connected and then to do a little range testing.

Until next post,

Randy
