[TR] battery and charging system

[bill beecher]

 All the good points that Glenn made.  Also, bit elementary, but re-check all your cables/wire connections  to be clean and tight.

With the engine ON and running over 1200RPM, you should have ~ 13.8 to 14.8 Volts Direct Current (VDC) reading on your meter across the battery terminals.
 
With the engine OFF,  a good battery will read ~12.6 VDC
 
Check and fill the electrolyte level of you have removeable caps, then put the battery on an overnight charge, get it to ~12.5 VDC, then try again.  Most alternators are not rated to charge a dead or dying battery and sometimes you will toast the regulator if it is trying to charge a low or dead battery.
 
Could be the alternator itself or alternator regulator.
 
Newer cars – some – will drop the charging if the battery load exceeds the rating of the alternator, others will just attempt to supply whatever the current load is until they burn out something.  My Jaguar tells me both if the battery is low on start or if the charging system is not working after starting, the miracle of technology.

If the battery reads 11.33 v whether the car is running or not, that means either the battery or the charging system is bad, right?
