Battery voltage fluctuating with the turn signals is normal. The two 1156 bulbs draw about 5A when hot (~27W each), and at least double that cold, i.e. every time they blink on. The stock alternator is 55 or 60A iirc. You're pulling surges of a quarter of its high-rpm rating, and you're at idle (since you can hear the fuel pump) where it can barely keep up with the loads anyway. And when the voltage dips, the fuel pump slows down. A spark when connecting the battery is also 100% normal, and does not imply anything wrong, modified or otherwise. You're charging the capacitors in every electronic module, including the radio, ECU, fuel pump controller (I can't remember if that year has one or not), cruise control module, etc etc.

I've had several pumps in my 87 DL wagon in the last two years and they all begin to whine and moan after a few months but only when they get warm. The whine pulses up and down when the turn signals are on or when any change is made to the loading on the battery. The pumps all work great at first and are pretty quiet but eventually I begin to hear them after a long drive home from work. I just figure it is cheap pumps that quickly lose the gearing tolerance after a few thousand miles.

An aftermarket head unit will always create a tiny spark when connecting the battery. Other than that the fuel pump issue is either a poorly operating alternator, old wiring with resistance points or a battery that isn’t coping as well as it used to. Lastly could be some sketchy wiring done by a pervious owner. You’d really need to check out if anything was modified before your ownership. Eg: I have a Gen1 RS turbo Liberty (Legacy over your way) that someone used the door switch circuit as the earth for the aftermarket head unit. Whenever someone opens a door the headunit turns off as the circuit becomes active. Classic (*facepalm*). Cheers Bennie

After all that, the engine Runs Flawlessly, Stable and Reliable! As I explained at post Nº 3 above, I obtained another Weber 32/36 carburetor: So I changed it after a Decade, to test the Choke and Anti-Dieseling Fuel Cutoff solenoid: Photo of the finished install: Here is how the new Weber looks, already installed and Running smoothly: And This is How my 1985 Weberized EA82 Subaru Wagon Looks Now: Named: The "BumbleBeast" Here's the Build Thread: ~► http://www.ultimatesubaru.org/forum/topic/122276-the-bumble-beast/ This is a Video of the Weber Carburetor, Working on my "BumbleBeast" Subaru: Feel free to ask Any questions regarding the Weber Carb Swap, on its Discussion Thread, which is Here: ~► http://www.ultimatesubaru.org/forum/topic/148641-to-27-loyale/ I Hope This Write-up will be Helpful.
