ac compressor causing short RB25

[e_Dog]

Hi all,

A/C fuse keeps blowing. Several auto eleces have had a look and not been able to fix. Last one is know saying that the compressor is causing a short and needs to be replaced and partly because i dont feel like replacing it just to check he's right plus i cant actually find a second hand one, means im wondering if theres any way to know this is the actual cause and if theres any way it could be fixed without replacing.

Bit more info; 10amp fuse blows nearly straight away, 20 amp lasts about 15-20 minutes. Clutch is engaging, everything is working fine when the fuse is still functional.

Help please, i paid dollar bills ya'll to have this a/c installed (engine swap, had no ac originally) and havent had fully working ac for 2 years

Fit 10A fuse. Disconnect compressor. Turn on Ac and see if it blows. Or go for a short drive like this to see if it lasts.

Good idea, will do now.

Measure the resistance of the magnetic clutch. Should be around 3.5 ohms. If it's much less then there's a short.
