by electrical smell you mean what ? burning insulation ?
before you do anything, check all your connections [both battery terminals, the ground at the block and the starter, the positive at the starter, the positive at the alternator. check all the wiring for obvious shorts and damage. squirrels love to make nests and or climb on warm motors and chew wiring.
with the car off check the battery voltage, multimeter on dc volts setting, should be over 12 v .
start the car and check the voltage at the battery again, should be at least a volt higher than it was. generally it should be in the 14+ volt range when charging. if it's too high that's not good either as that will boil the electrolyte and "cook" the battery.
if that doesn't tell you what you need to know, most decent auto parts stores will load test your alternator for free
