Trantec Pack problem

[ptheboris]

Hi

 

Just wondering if anyone has ever had a case of a Trantec S4000 that has refused to work.

 

Basically what happened is that the signal was lost half way through performance yesterday. The battery was changed on the assumption that it was dead. The pack came back to life and just died again. Three new batteries later it was still dead. There is very brief signal without the back of the back on but it goes when closed up again.

 

A friend mentioned that this was a problem with the trantec pack design. Anybody got any ideas as to what the problem may be?

 

I have contacted the supplier of the equipment about the fault but wanted so see if anyone had come across this problem before.

 

regards

The battery contacts put a strain on the pcb, well worth resoldering the pads, easy to get to. Solved my cutting out problems every time.

The last Trantec packs I used (can't remember the model) had been repaired, using the cheap snap-on PP3 connectors found in Maplin. This was all very well, but the cables had been crushed and sliced through years of opening/closing the battery compartment, to the point where the insulation had been worn away and the wires were shorting.

 

Easy way to detect this (without a multimeter) is much popping from the mic during the show, and a VERY warm PP3 cell when the inevitible change is required...

 

Still, should be easy enough to sort.

Interesting... I've got a problematic handheld. I'll check the soldering, before it hits the bin!

Further to this. Just found the battery is a carbon zinc PP3 but as I understand it this should make no difference to the operation of the mic. Is this the case?

 

All the other batteries in use have been alkaline though one has had a carbon zinc in and works fine.

Only difference is carbon-zincs have a slightly lower output voltage, but not significantly so to affect operation like this, have you tried it with an alkaline?

Shouldn't make too much difference to the operation, but the battery life won't be up to much!

Many thanks for the replies. It turned out it was the battery terminals that were causing the problem. General wear and tear over time as batteries get changed.

 

THanks again
