So, I put in a 10si 78 amp alternator and electric fan, moved the battery to the trunk, and replaced all the dead bulbs at the back of the car. Next day my battery is dead (which leaves a lot of options)

The dead battery might be a couple of obvious things like inadequate ground so I added a strap from the alternator housing to the firewall to go along with the one from the blosk to the firewall on the opposite side. Could be diodes in the alternator but I am not ready to give up on the brand new alternator just yet. I should mention that I bought a triple gauge set that will be going in soon so that I can monitor the potential difference (I have an ammeter too but it only marked for 60 amps and I am not sure I won't wreck it with a 78 amp alternator). My fuel gauge worked for a lot longer than ever before anyway :)

The next day I started to get mad clicking from the dash area. Turns out it is the overdrive relay on the firewall?! So, I go to the parts store because I am thinking new relay (I don't know if I really want to sort this out right now). They can't cross the numbers from the relay and I am thinking disconnect because I have not put the standard tranny back in yet and the relay shouldn't be doing anything anyway. So I start it up (mad clicking) and when I went to the trunk for the test light I notice the formerly dead-bulbed right reverse light is dancing to the tune of said overdrive relay clicking (the reverse lights were the only ones I could not get to work).

So, I am almost ready to put the four speed overdrive back in. In the meantime, any suggestions? I have not got a lot of time to devote right now as I have projects and then exams next week!! For now I have disconnected the live from the overdrive relay.
