'Allo 'allo,
Recently I have purchased a Mez H1/B2 that was imported from Czechia to the UK, and I'm going to try and get it up and running properly!

Amazing! I wouldn't worry about that crack as long as it doesn't affect the function of the siren, it's fine. i'd recommend either removing the stator or rotor (depending on which one comes off first), and trying to wiggle the shaft of the motor left and right gradually until it becomes loose. Be careful not to damage any of the components. Getting that rust off of the stator and rotor is a pretty big factor for when it comes to running, so it doesn't scrape the stator. Remember to check and oil the bearings. If it's a brushed motor, I recommend checking the brushes. Other than that, good job! Looking forward to seeing how this turns out.Eclipse DDS wrote: ↑Mon May 06, 2024 3:04 pmSo... there was a bit of an accident that happened yesterday when we were poking around the Mez...

Just thought I'd throw in a higher-quality image of the wire terminals too, if anyone could give any guidance regarding whether they're correct that would be very much appreciated!

Ah, I see, thanks for the information! An interesting thing about this siren that I keep forgetting to mention is that the stator and motor surround is all a single-cast part, so to be able to get at the motor we'd have to remove the rotor anyway, which is the next thing we'll be doing. Repairing or replacing the bearings is going to be the next step, as that is what is causing the siren to have a rumbling sound as the rotor spins. I'll post again once we get that rotor off and see the motor itselfTheVintageLouisiana wrote: ↑Mon May 06, 2024 3:19 pmAmazing!

EDIT: Didn't see the welding part. It is CRUCIAL to remove the motor during that so you don't accidentally weld the rotor and the stator together.
