A brush for a starter - generator comprising: a first carbon block having an outboard edge and an inboard edge, the first carbon block including a first front carbon wafer and a first rear carbon wafer contacting the first front carbon wafer; a second carbon block having an outboard edge and an inboard edge, wherein the inboard edge of the second carbon block faces and is adjacent to the inboard edge of the first carbon block, the second carbon block including a second front carbon wafer and a second rear carbon wafer contacting the second front carbon wafer; a terminal lug having a tab; a first front brush lead connecting the terminal lug with the first front carbon wafer, wherein the first front brush lead contacts the terminal lug at the tab and the first front brush lead extends into the first front carbon wafer adjacent the inboard edge of the first carbon block; a second front brush lead connecting the terminal lug with the second front carbon wafer, wherein the second front brush lead contacts the terminal lug at the tab and the second front brush lead extends into the second front carbon wafer adjacent the inboard edge of the second carbon block; a first rear brush lead connecting the terminal lug with the first rear carbon wafer, wherein the first rear brush lead contacts the terminal lug at the tab and the first rear brush lead extends into the first rear carbon wafer adjacent the outboard edge of the first carbon block; and a second rear brush lead connecting the terminal lug with the second rear carbon wafer, wherein the second rear brush lead contacts the terminal lug at the tab and the second rear brush lead extends into the second rear carbon wafer adjacent the outboard edge of the second carbon block, wherein the brush defines a mirror image line positioned between the inboard edge of the first carbon block and the inboard edge of the second carbon block, characterized in that each of the brush leads (80, 82, 84, 86) converges toward the mirror image line along the respective brush lead moving from where the respective brush lead extends into the respective carbon wafer in the respective carbon block toward the tab of the terminal lug. a first carbon block having an outboard edge and an inboard edge, the first carbon block including a first front carbon wafer and a first rear carbon wafer contacting the first front carbon wafer; a second carbon block having an outboard edge and an inboard edge, wherein the inboard edge of the second carbon block faces and is adjacent to the inboard edge of the first carbon block, the second carbon block including a second front carbon wafer and a second rear carbon wafer contacting the second front carbon wafer; a terminal lug having a tab; a first front brush lead connecting the terminal lug with the first front carbon wafer, wherein the first front brush lead contacts the terminal lug at the tab and the first front brush lead extends into the first front carbon wafer adjacent the inboard edge of the first carbon block; a second front brush lead connecting the terminal lug with the second front carbon wafer, wherein the second front brush lead contacts the terminal lug at the tab and the second front brush lead extends into the second front carbon wafer adjacent the inboard edge of the second carbon block; a first rear brush lead connecting the terminal lug with the first rear carbon wafer, wherein the first rear brush lead contacts the terminal lug at the tab and the first rear brush lead extends into the first rear carbon wafer adjacent the outboard edge of the first carbon block; and a second rear brush lead connecting the terminal lug with the second rear carbon wafer, wherein the second rear brush lead contacts the terminal lug at the tab and the second rear brush lead extends into the second rear carbon wafer adjacent the outboard edge of the second carbon block, wherein the brush defines a mirror image line positioned between the inboard edge of the first carbon block and the inboard edge of the second carbon block, characterized in that each of the brush leads (80, 82, 84, 86) converges toward the mirror image line along the respective brush lead moving from where the respective brush lead extends into the respective carbon wafer in the respective carbon block toward the tab of the terminal lug.
