Hi,
I just rebuilt the brake and clutch master cylinders. In the process while positioning my trouble light, I blew out one of the fuses in the main fuse box. I replaced it with what I thought was an acceptable spare. After stopping for the night, the fuel pump was running without the ignition switch on. I noticed the gas smell and pulled both fuses the next morning. The car starts and runs fine which I know has nothing to do with the fuses in the main fuse box. Why would the fuel pump have been running without the switch on? What are acceptable replacement fuses?
Thanks,
Chuck Keeler
 
What are acceptable replacement fuses?

Britsh specs are: 50 and 35 Amps.

Equivalent American fuses are: 35 and 25 Amps
 
The fuel pump is unfused but switched by the ignition key. When you blew the fuse, you caused a dead short that may have caused a melted connection within the ignition so that now it is always on. I would use a ohmmeter to check out the circuits. Did pulling the fuses shut off the fuel pump? I would need more info to be of more help. Other more expert may post better answers.
 
I suspect that you inserted the fuse *between* the two (2) sets of fuseholders. This has the same result as switching on the key.

Yes, your Healey is that easy to "hotwire" (energizing the ignition and fuelpump).

Or, the troublelight (I hate those &^%$# things) bent one or more of the holders causing them to make contact.

You can insert a "quarter" between the fuse conections making the Healey an easy car to hotwire. Best 25 cent ride you'll ever find.
