Given a Galois cover of curves over $\mathbb{F}_p$, we relate the $p$-adicvaluation of epsilon constants appearing in functional equations of ArtinL-functions to an equivariant Euler characteristic. Our main theoremgeneralises a result of Chinburg from the tamely to the weakly ramified case.We furthermore apply Chinburg's result to obtain a `weak' relation in thegeneral case. In the Appendix, we study, in this arbitrarily wildly ramifiedcase, the integrality of $p$-adic valuations of epsilon constants.
