Driver heating up?

[OutlawZ]

I looked in the search bar already and i couldn't find anything specifically about this... My driver is heating up i think it's at 120mA mohrenberg set it to that i bought a complete module from him.. anyways my diode is dim and it doesn't even look like it's going 1mW honestly... The driver is a rckstr driver...

What kind of batteries?

 

[OutlawZ]

They're 10440's, but jayrob and rckstr said it was fine to use 3 10440's in the mxdl 3405 host because it would drop the voltage to 12v really fast anyways

 

[mfo]

Kind of sounds like you have a fried diode TBH. Did you wire it correctly? Jay also told me the same thing but I soldered a diode in there just to be safe cuz I have bad luck.

 

[OutlawZ]

What does a "fried" diode look like then? I mean it was working before great.. but when i got the charger from flaminpyro and charged them it got dim.. also it started getting dim before i charged the batteries as well and it was flickering

 

[mfo]

A fried laser diode looks exactly like what you're describing, a very very dim dot. Can you disassemble the host and test the module with a 9 volt battery?

 

[OutlawZ]

I don't have a 9v battery on hand..well this sucks.. i guess i have to build another one.. i don't really feel like having to get a flexdrive and then some rechargeable 1.5v batteries and then soldering the diode.. all seems really expensive.. i guess i give up this hobby...

 

[mfo]

Take out one of the batteries from the holder, and bypass it with a piece of wire so in essence you'll be using 2 batteries instead of three. Tell me what happens.

 

[OutlawZ]

It won't even start up if i do that

Something is definitely wrong then. Sounds like your driver somehow fried, which in turn killed your LD. You have a volt meter on hand?

 

[OutlawZ]

Yeah the batteries are all good.. i do not have a test load though

 

[mfo]

What is there voltages each?

 

[OutlawZ]

4.14v 4.12v 4.11v

 

[OutlawZ]

So, i'm just wondering... i guess it's my fault? Or it's still my fault that i didn't install a diode referring to the diode on the driver...that's $20 gone.. not bad i guess... just doesn't work anymore...sucks bad!

you should try contact Mohrenberg,as long as you did it all correct the problem was the diode or the driver.

 

[OutlawZ]

Ok, i guess i will go and try that...
