Bypass ampmeter through bulkhead

How much current does the battery draw? and for how long?
How much current do the other items draw? and for how long?
As for as the accessories. During shows and contest. The only accessory used is the original AM radio. No heater being used. As I only drive it during the day and with good weather. And during spring and summer.
OK. If the lights, wipers, heater fan are never used then the current loads are as follows:
Ignition and field current - approx 5 amps
Brake lights - about 4.5 amps
Turn signal - which turns off one brake light and is also briefly used we'll ignore it.
So that's about it for your projected uses.
For someone running the heater fan, lights, etc, the alternator will need to provide 25 to 30 amps to run them all at the same time.

The battery after starting typically draws 15 amps to 20 amps for less than a minute. After 5 minutes of driving it draws basically zero. Depending how long it had to crank it could be a little more or a little less.

The bogeyman only appears in your imagination. And comes to cause doubt.
Not mine. :)
I'm not the one saying the ammeter is going to blow up people's cars or set them ablaze. LOL
I am saying a working ammeter provides useful information. In fact if one pays attention, an operator can spot problems early and can even avoid a meltdown due to overcharging or a short.
With the charging current bypassing the

“ampmeter “. The chances of any issues are slim to none.
