I will start this post by saying, 'No Venture parts were harmed in the making of this post, however there was an unfortunate VMax casualty' Pictures attached are of a group of solenoids from a MKI, MKII Venture and VMax. 1st picture is of on left an MKII Venture, middle is I believe an 83 Venture (probably similar to 84-85), and on the right is a VMax solenoid. [ATTACH]61706[/ATTACH] Next is shown why the MKII's only need 1 wire in control circuit, on the right side there is a jumper from the coil terminal to the large terminal that is connected to the positive battery. The MKI's and the VMax's have two wires in the small coil control circuit. The MKII circuitry is all done on the 12V- side. [ATTACH]61707[/ATTACH] This picture shows the VMax solenoid split in half. Right right side is the coil, plunger & spring. The two small studs are for the control circuit wires. Left side is the main contact set. The two silver colored pads are the tops of the studs the main heavy starter circuit wires are attached to. Between the two silver studs is a plastic plunger nub for the copper contact plate between the two studs. This plastic nub keeps the coil plunger from contacting the two stud tops when the coil is de-energized. Normally the spring in the coil side keeps the plunger in a position to press down on the plastic nub and break the connection between the two studs. [ATTACH]61708[/ATTACH] This picture shows the plunger and spring removed from the coil pack on the right side. On the left side is the two studs removed and the copper contact plate that completes the circuit. Notice the dislocation from arcing on the stud base to the left. This carbon build up is enough to cause failure of this solenoid. Not obvious in the picture is a spring in the contact black housing in the center hole. This spring pushes the copper contact plate into two stud bases when the coil is energized. [ATTACH]61709[/ATTACH] This picture shows a closer view of the contact side. Arcing damage to stud faces is more visible. [ATTACH]61710[/ATTACH] Gary
