Yes they are repairable. I have a guy na kumakatay ng alternator right before you're eyes. In a matter of hours you'll be up and running again. At least sure ka na ginawa ang problem unlike sa surplus na medyo sugal.

The shop is Mang Anselmo's Electrical sa Roosevelt. Near Pantranco Quezon Ave. Katapat niya yung ice plant. As he is a small time shop (cottage industry), he doesn't have an office nor a telephone number (his house has pero hindi ata pinapamigay). Madali lang siya hanapin since he is also the kagawad of the branggay (sikat!). hehehe.
