Need help on Griffin schema about 2 resistors after power connector - GSM-Forum

Burnt Cobba · 02-13-2003, 19:00

mate anyoen can tell me what are teh values of the 2 resistances (same value both) that are jsut after teh pwoer supply connector?

must they be low power or it does not matter?

thanks a lot

I had same problems.

Please check my past posts and you will find answer

well i am ashamed to tell this but these resistors for some reason eh...... literally burnt up. I never had such a thing happen.

i take care for the equipment. Hope to replace them and maybe fix the box once and for all. At least i must say that the producers ofthe griffin box did the box in a maintainable way. Well done for the design.

thanks for the help

changed them and also a ****n up diode IN535 it is powering up ok however it is failing to flash. It is recognising phones now and can power up the phones ok eh.

seems need more trouble shooting.

Hiya

Maybe too late but resistance of both is 67kOhm...

Have already told you cannot supply high voltage to Griffin Box,
you will 'Burn' the box, those 2 resistors are 2 Ohm.
If you have already replaced the resistor but the Box still not
work, that means, you have also 'burned' other components.
There has no 67K Ohm resistor inside Griffin Box !!!!

mates it is powering up ok but i have a ****n up diode i cant figure out what it is... it is near the power onnetor too.. a BIG black diode.

1N535X

the X is from 0 to 9. Anyone can check pls? I changed it with notehr diode but it is incorret. It can recognise phones ok but nat flash them

.

Thanks for the help and support

Hiya

This was misunderstanding....I was speaking about 2 resistors in dummy battery for dct4. Both of them 67kOhm and simulating battery temp.

It is 1N5350, I have said, may be another components was
damaged in your Box, not only these two 2 Ohm resistors
and this 1N5350 !!!!
If you have some basic electronics skill, you should know what's
the purpose of this 'Diode'...
Even you don't replace (or without) this 1N5350, the Griffin Box
can work for both unlocking and flashing if there are no other
faulty components !!!!

Thanks for the reply cables

I am trying to fix it so as to avoid sending it back. At first it did not even detect phones at all. As it is it is detecting them.

I tried to contact you via ICQ mate but had no reply.
