T2 Plunger blowing fuse....


LAP

Question

Trying to help a mate fix his T2 plunger which recently stopped working....

 

A little bit of knowledge is a dangerous thing (that's me) anyway need to throw it out there to get some help...

 

Plunger got weaker and weaker and then stopped all together....

 

First I checked the wire connections and they were all good.

 

Next checked the fuses and one was blown so replaced it.... thinking I was done turned the machine back on and pop... fuse went again.

 

I then disconnected the plunger solenoid and replaced the fuse again and fuses did not blow.

 

So my basic knowledge says the solenoid is done.... but wanted to check the solenoid did not burn out because of another issue.

 

Where to from here?

 

Thanks

You can replace the coil but you would want to make sure it doesn't lock on when the machine is turned on.

Have you tested the coil resistance with a meter?

It shouldn't be less than 2 ohms but should really be more like 4 ohms.

Generally the plunger will be jammed if the coil is melted.

What fuse was blowing?

There could be a board fault too.

Just hooked the plunger wires up to the multi meter and in test mode the voltage is stuck on 70ish volts.....

 

The voltage is always there, 70v is correct

The board grounds the coil to fire it (thin wire)

Not sure why F103 is blowing, are you sure it's not F104? It should be a 3A Slow Blow fuse

The plunger is solenoid 9, fuse F104 handles solenoids 9-16

2.6ohms is too low, should be 4.2ohms

When I check the voltage on the kick buck plunger in test mold the voltage pulses (can't really see what voltage as its so quick) but on the plunger solenoid wires in test mode seems to be 'stuck' on 70ish volts ie does not pulse in test mode is that normal?
