Compressor start kit

Morning

Anyone point me in the right direction for a decent hard start kit for CSR comps.

This will be for testing purposes only, I’ve seen NOR CAL REFRIGERATION use a Handy little rig but they appear to be unavailable.

Any help would be appreciated 🍺

Size of compressor?

Various comps, mainly small bottle coolers, 2-3 door freezers etc.

I just want something I can quickly and efficiently test the comps before ripping the start kit to bits.

Connect it direct to the mains eventually with a capacitor and use a small switch to engage the start winding for 1 second
