[Bricklin] Electrical Questions Alternator and Air system

 Yes, you can test with a multimeter and should get around 14 volts at the
battery with the engine running. Here is a video that demonstrates that:

What voltage are you getting at the battery with the engine off? A good
battery should put out around 12.5 volts. It sounds like you may have a
problem with the battery, the voltage regulator, or maybe a wiring problem
such as a bad ground. It is possible your replacement alternator is bad too,
but that seems less likely. Most parts stores will test it for you free.

Just an update.  I have replaced the bent valve and now everythig is running

well.  At least engine wise.



It seemed my alternator was not keeping my battery at full charge.  I checked

it with a volt meter while running and I was seeing 11.95-12.00 on the

voltage.  I was expecting a higher number like 14 volts.  I replaced the

alternator and after installing I am getting a similar reading but a little

less 11.85.  Is this the correct way to check the alternator and is the

voltage correct or do I need to replace this one also?



My other issue was after driving around I opened my door and I could hear the

air pump running.  Normally when it gets below the pressure switch range it

runs for a short time and cuts off.  This time it would not stop.  I pulled

the fuse to the pump to get it to stop.  I checked my tank pressue and it was

at 190 lbs.  I reduce the pressure down to 90 and resinserted the fuse and it

ran up to 150.  It almost seems like the relay was stuck in the closed

position or possibly the pressure switch.  I had installed a Viar 425c to

replace the small pump.  The nice thing about the small pump it would run to

about 115lbs and stop.  With this new pump it has so much power I am not sure

when it would stop.  It also has a lot of power draw so I do not recommend

this model.  I would go maybe with a 200 series or possibly less. Has anyone

had this issue?



I plan to swap the relay and I may replace the pressure switch with a air

pressure gauge and just work the pump with my auxillary switch so  I can

control when the pump comes on.  I have had this system installed for a while

and I just left it where it would come on as needed.  Now I am concerned with

the pump not stopping.
