SDS Drill working intermittently

As above drill comes and goes as it pleases.

Bushes look good.

Cleaned the switch with contact cleaner but still happening.

Any ideas?

Its a Challenge 1300w

Overheat sensor could be bust?

Or loose cables in the power line

I'd nearly put money on a broken wire where the power lead enters the drill.
I think I have the same drill and for what was tiny money 10 years ago, it has been great.

Lol ya I bought it about 8 years ago and it is an absolute work horse.. paid €46 for it so has paid itself off times over.

I opened up and all wires look intact, will do some more digging tomorrow.

Anyway to diagnose an overheat sensor?

It may not have one but look for a thermistor two cable sensor ends tend to be white. But again not all sds have them tend to be in the most expensive models

I would also bet that its the lead where it goes into the body. I think its the short lead on them and that you are often drilling reasonably high

I have an aeg drill I bought years ago. I'm waiting for it to die before I buy a better one but it keeps on going. I thought it was on the way out last year when it started revving up and down and cutting out. turned out to be a broken wire . fixed that and its perfect. shame because I bought a cordless one so the aeg only comes out once a month

I would be 99.99% sure a new flex from plug top to drill will solve your problem.

It's alive!

About 10 inches back from body one of the wires had an internal break. Took a bit of experimenting to find it.

Thanks lads

The reason I recommended replacing the whole cable is that after 8 years of being a workhorse, there are probably other spots where there are some strands broken.
This causes hot spots in the cable and will probably lead to the same problem again.

They really are a solid piece of kit at a stupidly cheap price.
I've seen stuff 10 times the price give more trouble.
