Help , I have a 1973 Wisconsin LP VG4D ( Serial # 5301773 - Spec #338511) connected to a Winco 15 KW 3 Phase Alternator / Generator ( Serial # E - 0986 - A4 / MODEL # 18 WS - 4 R/A ) 120/208 60 Hertz @ 1800 RPM ) This a project That I had started last year and has been bothering me that I was not able to finish. I did receive help from this site , but like I said its been a while. To start off since the engine would not spin I thought that maybe the alternator was stuck so I separated the engine and gen set only to find out that the engine was stuck , after trying all types of distillates with no results I removed both aluminum heads off but not before shearing 8 bolts on one head and 9 bolts in the other.
After drilling and tapping ( Many broken bits) I now have the entire unit back together and I find myself at a stand still , :wave : with regards to the wiring on this engine as well as the generator. This unit came from a municipal building which was set up with an auto start / automatic transfer switch . I apologize for such a lengthy post but I felt you should know the history . There are 2 wires coming off the LP solenoid 1 gets attached to the small post ( there are 2 small posts and 2 large posts ) on the starter solenoid the other is connected to one of the 5 wires coming from the front of the gen set , the start switch (Toggle) has 2 connections ( on the start side ) , 1 is the mag the other is to the head. Now on the ( stop side ) there is 1 wire that is grounded to the block. There is more , there are still 4 more wires coming from the front of the gen set . 1 is grounded , 1 is connected to the the large post along with the positive cable and 1 on each of the small posts.
Last but not least there 2 wires coming from the back of the gen set , 1 is white which was taped to the negative cable the other is black and is connected to the large post along with the positive cable and 1 of the wires from the front of the gen set for a total of 3 on one of the large post. The starter is hooked up to the other large post .. This is making me nuts. PLEASE HELP
