Hi. The leads on my recently acquired strobe light are too short to reach the battery. Is there a suitable source of power under the bonnet.

No. 4 fuse is live on my ‘78, I usually just hook it on there an earth it on the alternator bolt.

A word from me about my experiences! With the MGB batteries being a long way from the engine I used a power source from the fusebox. I found that the strobe rpm readings (and perhaps the dwell etc) were unreliable. I've never found out why, but eventually used a spare 12 volt battery to get around the problems. The strobe was a Sealey item. Using a spare 12 volt battery everything worked as expected.

Just dont do what i did; buy a new strobe light and get perplexed why the reading kept changing, not realising the thing had an advance control at the back which kept getting knocked and moved.

I found the lack of a good 12v terminal under the bonnet a nuisance, so on my V8 I have fitted one of these https://www.vehiclewiringproducts.co.uk ... x-two-stud and have run a starter sized cable from there down to the main terminal on the starter motor. Thus it connects directly to the battery. The box is mounted with a screw to the pedal box (see photo) and with the snap shut lid is quite safe from accidental short circuits. Not only is it a handy power source, but I charge the battery from there too.

Thanks for your inputs. I suppose the easiest thing to do, in view of the amount of times that this operation will be done, is to park my other car close to the front of the B and use the other cars battery as a power source for the strobe.
