It happened again! for the third time, the resistor pack packed up. It wasn't even hot weather, but I was caught in a long traffic queue. This time I'm not going to fork out silly £60 for a new part. I'm going to replace the diode on the pack. It is tricky because it has to be wired without soldering as the environment is hot. But which diode should I use; what are the required volt/amp data?
Pass on the diode type (although we may assume it is a silicon utility model). As to the soldering: _how_ hot do you expect it to get in there -- ordinary solder melts at, what, 300C+ ? But if you do the job, try to use a temperature-controlled iron (eg Weller) and consider applying heat shunts whilst soldering. And, of course, use decent multicore solder. (Or am I teaching granny's grandpa how to suck eggs?)

This is the problem, the text is not readable. I may assume a heavy duty
10-20 amp spec silicon type, but it would be nice to know.
No problem applying some solder, I have all the gear, but the resistor pack obviously gets very hot while operating. This is the reason they fail in the first place.
